They are really too low!

Kasugano Sora, his younger sister.

Of course, the two are not biological siblings, as can be seen from their names.

The reason is simple: Hoshino Mi is actually Kasugano Sora's neighbor and older brother, or rather, Kasugano Sora was a child who was fostered by him for a period of time.

A few years ago, Hoshino Mi inexplicably traveled to this world and became Kasugano Sora's neighbor, and was also an orphan.

Kasugano Sora was frail and sickly from a young age, and was frequently hospitalized. She had no friends her own age and spent all her time facing the hospital ceiling, with almost no communication with anyone.

When Hoshino first saw Kasugano Sora, he suspected that the child might already have psychological problems. It took him several days to finally get Kasugano Sora to smile.

A month later, Kasugano Sora completely regarded him as her older brother.

However, this also led to Kasugano Sora's parents being extremely pleasantly surprised by him, and they treated him almost like their own child.

Because Kasugano Sora's parents went to Germany on a business trip this year, they entrusted Kasugano Sora to Hoshino Mi's care for a while, and the two ended up living together.

Hoshino felt something was off. He was, after all, a normal boy. Weren't they being far too trusting of him?

"Brother, where's your coat?"

Kasugano Sora's voice brought Hoshino back to his senses, and he noticed that his adopted sister was frowning.

"I saw someone getting wet in the rain on the way, so I lent them my jacket temporarily," Hoshino said, keeping the conversation brief and vague to the young woman.

"Mind your own business. Only an idiot would get caught in the rain on the street," Kasugano Sora said, somewhat displeased. "Brother, don't meddle in things like this next time."

This younger sister is really harsh and ruthless towards people other than him.

Hoshino recalled Toyokawa Shoko from earlier; she was soaking wet, even her little leather shoes were wet, and it was hard to leave her alone.

Besides, he had already received the reward.

"Never mind the coat for now, how long are you going to stick to him like this?" Eriri picked up the game controller next to her. "Let's finish this game already, we've been playing for hours!"

"No, your skills are terrible, you can't even jump up the steps." Kasugano Sora showed a disgusted expression. She ran to Hoshino Mi's side because Eriri's gaming skills were too bad.

"If you don't play, I can't play by myself!" Eriri glanced at Hoshino Mi casually, then naturally turned her gaze to him. "Why don't you play with me, Mi-kun?"

Upon hearing this, Hoshino felt Kasugano Sora release him from her arms.

"No need to trouble you, brother. I'll play with you instead." Kasugano Sora casually left Hoshino Mi's side, sat back down on the sofa, and picked up the game controller.

Eriri pouted, looking somewhat disappointed.

Hoshino glanced over; they were playing a popular two-player game.

Because Eriri often came here, Kasugano Sora and she developed a fairly good relationship over time.

More importantly, both of them are homebodies and have a lot in common, watching anime and playing games together.

Especially after learning about Kasugano Sora's situation, Eriri treated her almost like her own younger sister, and the two had a particularly harmonious relationship.

At this moment, Hoshino finally had time to return to the game window.

[Player: Hoshino Mi]

【Charm: 32】

[Stamina: 15]

【Intelligence: 20】

[Skills: Cooking (LV2), Writing (LV3), Painting (LV1), Music Theory (LV1), Sensitivity (Special)]

Ever since Hoshino Mi traveled through time, this thing has inexplicably appeared before his eyes as well.

This thing not only lacks a beginner's tutorial, but it also doesn't come with an instruction manual.

After studying it on his own for a long time, Hoshino finally figured out the basic gameplay.

Like some bishoujo romance games, as long as Hoshino increases the intimacy level with the bishoujo, the system will give him a reward, from which he can choose one.

For example, when it came to Toyokawa Shoko just now, Hoshino Mi chose the "Music Theory (LV1)" skill, and a bunch of basic music theory knowledge immediately flooded his mind.

Hoshino Mi, who couldn't understand sheet music before, will probably be able to read it without any problems now.

Hmm, who would give up such a powerful skill to choose the little leather shoes that a pretty girl has worn all day?

Hoshino naturally chose the more practical skill. To him, each beautiful girl was a huge treasure chest from which all sorts of rewards could be obtained.

However, even these huge treasure chests have their limits. Intimacy is like a boss's health bar; going from 10 to 20 is a new stage, and going from 20 to 30 is yet another new stage.

Hoshino's understanding of this is that it is a continuous improvement from unfamiliarity to familiarity, and then from familiarity to friendship, symbolizing that the relationship between the two parties is becoming closer.

The system will only give corresponding rewards each time you advance to a higher level.

Based on Hoshino's experience, Kasugano Sora and Eriri are both just one step away from getting the next stage's reward.

Unfortunately, Hoshino couldn't budge the two of them. They'd been stuck here for two or three years, as if they'd reached some kind of limit.

To be honest, this card actually made Hoshino even more curious.

How exactly can I push the intimacy level to 100%, and what will happen after the intimacy level reaches 100%?

With this in mind, Hoshino was constantly exploring more ways to play, trying to find a way to achieve a 100% success rate in the strategy.

For example, it's easier to get along with someone you're meeting for the first time. Once you successfully break the ice and make an impression on them, Hoshino can get the first stage reward for free.

The perfect example is Toyokawa Shoko, whom I happened to meet today. As long as she makes a strong impression on Hoshino Mi, the intimacy level will be practically free.

However, the subsequent strategies will need to be developed gradually.

Hoshino wasn't in a hurry. He had already exchanged contact information with Toyokawa Shoko, who insisted on returning his coat to him in the next few days.

Hoshino glanced at the two girls in the living room, then took the shopping bag back to her room.

……

After finishing the game, Eriri was quite satisfied. She stretched and revealed a small section of her fair and soft waist.

Seeing Kasugano Sora lying on the sofa, Eriri seemed to have thought of something. She secretly picked up her phone, took a picture of the game ending, and then opened a group chat called "Love Strategy".

"Iron-Blooded Green Plum Party: Photo.jpg"

"Iron-blooded childhood sweethearts: I played games with my childhood sweetheart at his house today, hehehe, I'll get to eat his homemade food again later!"

After sending the message, Eriri felt a little pleased with herself.

Immediately afterwards, someone replied.

"Super Pretty Girl: ?"

"Super Pretty Girl: No, is the little virgin starting to daydream again?"

"Super Pretty Girl: ???"

Eriri blushed slightly in response to the ridicule from her group members and quickly typed on her phone.

"Iron-Blooded Childhood Sweethearts: Believe it or not, I still have previous photos!"

"Iron-Blooded Green Plum Party: Photo.jpg"

This time, Eriri specially posted a photo she had secretly taken of Hoshino Mi before. Her face was not shown, but there was a close-up of her hand, showing her well-defined knuckles, slender fingers, and faint blue veins.

As soon as the photos were posted, everyone immediately started commenting.

"Huali: You have quite the imagination to keep up with the trends. Where did you find this online image?"

"Do you want ice cream today? You really need to pay attention to this. I have a friend who had these symptoms before, but she didn't take it seriously and went to bed as usual. She only woke up the next morning with these symptoms!"

"Super Pretty Girl: You know what, her hands are actually quite pretty. I want to lick them."

Water Mage: Brother, I can do it!

"Robelia: Suddenly you're on my word, sis, is there anything else?"

"Innocent Kitten: Your childhood sweetheart is so handsome, waaaaah, I can't stop touching him..."

Seriously? You bunch of weirdos in the group can actually trust her childhood sweetheart?!

Chapter Three: Perhaps it's better to take medicine?

"Iron-Blooded Childhood Sweetheart Party: Shrimp Head Girl, calm down, is this really my childhood sweetheart??"

"Super Girl: What do you mean, your childhood sweetheart? He's in my phone now, so you have no say in the matter!"

"Water Mage: I've already taken my skirt off, and this is what you're telling me.jpg"

"Innocent Kitten: It wasn't me, I didn't do it!"

"Iron-Blooded Childhood Sweethearts: Go ahead and charge, you'll only hurt yourselves in the end.jpg"

Eriri pouted. She had been in this group chat for half a year. The group name seemed to be a serious dating guide, but in reality, the group members were just being crazy and lewd every day.

As long as she posts Hoshino Mi's photos, these group members will become even more obnoxious.

At the beginning, everyone was very polite to each other, often sharing makeup tips and desserts, and even enthusiastically discussing topics related to love.

Later, everyone gradually realized that the group members were all inexperienced chatterboxes, and the style of the group chat began to become strange, with everyone revealing their true nature as a homebody who surfed the internet extensively.

Every day it's the same old thing: "Yay, I can do it!", "Waaaaah, I got the sheets wet again today!", "Does anyone have any erotic pictures?", "The first thing I do every morning is take a shower!"...

Eriri was already used to these shrimp girls. Although she saw them saying they were going to seduce Hoshino Mi's photos, she felt a little smug.

Hmph, you can only look at the photos and be envious, while she gets to see the real person every day!

It's obvious who's better!

Thinking of this, Eriri couldn't help but laugh, but then she tried her best to control her emotions, remembering that she wasn't in her own room.

Suddenly, someone tagged Eriri.

"Sayuri: Hey, to be honest, I've seen Qingmei-chan post pictures of her childhood sweetheart a lot since before, hasn't she won him over yet?"

These words struck Eriri's heart like a violent blow, shattering her good mood into nothingness.

Damn it, this guy is way too perceptive!

Eriri was very unwilling. In fact, she also wanted to win over Hoshino Mi as soon as possible, but the two had been together for seven or eight years, and Hoshino Mi just wouldn't make a move on her!

The two first met in the third grade of elementary school when Hoshino Mi came to her class as a transfer student and happened to sit next to her.

At that time, Eriri was almost completely immersed in the world of anime and manga because of her mother's influence. Unfortunately, no one around her shared the same hobby, and she couldn't find any friends to talk to, which made her very distressed.

However, Hoshino immediately recognized her as a hardcore anime otaku by looking at her pencil case and took the initiative to talk to her.

At that time, Eriri never expected anyone to talk to her about this topic. In her excitement, she revealed her identity without reservation.

Hoshino was also very interested in anime, and the two became very good friends. Later, Eriri even took Hoshino home and kept recommending the anime she was currently watching.

At the same time, she sent a lot of her collected comics to Hoshino Mi, and then she would often receive Hoshino Mi's evaluation of the comics the next day, which was almost the same as hers!

My goodness, this guy is simply a perfect friend sent to her by God!

Eriri was very happy. As her relationship with Hoshino became closer, she would often talk to Hoshino about anime and manga in class.

However, the two became increasingly withdrawn, and some classmates began to try to ostracize and bully them.

At that moment, Hoshino Mi still stood beside her, retaliating mercilessly against the child who was leading the attack.

Eriri felt she would probably never forget that scene for the rest of her life.

Especially during her early, awkward teenage years, she began to consciously collect anime and games featuring her childhood sweetheart and then immerse herself in them intensely.

Oh my god, this is totally me.jpg

Even now, Eriri has become a staunch supporter of childhood friends.

She won't read doujinshi that aren't about childhood sweethearts! She won't play eroge that isn't about childhood sweethearts!

Perhaps she got too caught up in the moment, because when Eriri came to her senses, she realized that not only had she not made any progress with Hoshino, but they seemed to have become good buddies.

Even so, Eriri certainly wouldn't honestly reveal the specific details when dealing with these group members.

"Iron-Blooded Childhood Sweethearts: I know you're in a hurry, but hold on a minute. Relationships take time. You bunch of inexperienced newbies, don't you even know what 'water flows naturally' means?"

"Super Pretty Girl: Huh?"

"Kari: Huh?"

Water Mage: Huh?

"Do you want ice cream today? Huh?"

"Super Pretty Girl: Seriously, is it true that some people spend years trying to win over their childhood sweetheart?"
