I really don't want to have a girlfriend.

If it weren't for this, she wouldn't have become increasingly bold, even starting to sneak into her brother's room and do those bad things...

It's all You's fault anyway! Who told him to keep going out lately, acting like he has a girlfriend? It's normal to worry, okay?

With her thoughts racing, Kasugano Sora snapped out of her anticipation and excitement and looked at her brother's gentle and handsome face.

"You probably don't have anything else to do today, right? There's a new game, and I need a teammate."

"Hmm? It shouldn't be..." Yuu Tenkuji was a little uncertain, and took out her phone from her pocket and swiped it.

Just then, a message came from Natsukawa Masaki.

"Critically ill, come immediately. Room XX, Building XX."

"..." Yuu Tenkuji's lips twitched slightly.

Is it because I set a flag for myself last night...? This guy actually caught a cold from being caught in the rain?

Before heading back from the hot spring trip, we should first visit Natsukawa in the hospital, right?

"What's wrong?" Seeing that he had only taken out his phone a short while ago and then showed a speechless expression, Kasugano Sora asked cautiously with a bad feeling.

Yuu Tenkuji shook his head, sighed, and put away his phone: "A friend of mine is sick and has no one to take care of him. I have to go out later, otherwise that guy might die at home."

Although it's a bit of an exaggeration, for some reason, Yuu Tenkuji has a premonition that if he doesn't go, Masuzu Natsukawa will become so sick that she's on the verge of death.

As her boyfriend in a transactional relationship, it's only right and proper for him to visit her when she's sick and make her some porridge or something.

Honestly, this is something girls should be doing.

"Friends...?" As if confirming something, Kasugano Sora stared intently at him. "Male or female? Yuihama?"

Tenkuji Yu's eyes were subtle: "Why do you think it's her..."

"Among your friends, she's the only one I know. If we exclude Yukinoshita, who you don't seem to consider a friend, and Totsuka, then..."

“That Totsuka… I feel like you’re really targeting him. But never mind.” Tenkuji Yuu pressed her temples and said helplessly, “It’s not Yuigahama Yui, it’s another friend.”

"Hmm, so is it a boy or a girl?"

Whoever that person is, that's what Kasugano Sora cares about most.

Chapter Sixty-Eight: Forget about the boat, you can't even push a person properly!

Yuu Tenkuji hesitated for a moment before honestly saying, "It's a girl, a transfer student who just arrived and has a very twisted and withdrawn personality. I guess she doesn't have any other friends to take care of her besides me."

"..."

As soon as he finished speaking, a powerful and profound aura began to emanate from in front of him, enveloping the entire living room.

That fair and lovely little face was half-shadowed, and her light-colored, glass-bead-like pupils were dull, as deep and quiet as a black hole. She just stared straight at him without blinking.

But the next moment, she returned to her usual calm demeanor, holding the black rabbit doll in her hands and saying, "Transfer student? You're quite popular."

“Indeed, I am aware of that.” Tenkuji Yu couldn’t help but chuckle, unable to be as self-assured as before. “Well… I’m just going to visit someone who is sick. I’ll try to come back as soon as possible.”

"No need." Kasugano Sora said in a flat tone, fiddling with her doll and not even looking at him. "It's only seven in the morning. As long as you prepare the food in advance, it's fine if you come back at eleven or twelve at night. I don't care."

If Yuuto Tenkuji were to take seriously what a girl says in a fit of pique, he would have wasted his two girlfriends who were almost ready to get married.

"Don't worry, no matter what happens to her, I'll come back to have dinner with you." Across the table, Tenkuji Yu reached out and patted her head. "No one can take your brother away, not even Yama or the summoning circle from another world—I've promised that from the very beginning."

"If you really don't want me to go there, then I'll pretend I didn't see this message and ignore whether she lives or dies."

After a moment of silence, Kasugano Sora sighed heavily, puffed out her cheeks, and hugged the doll tightly.

"...Yu, you're too cunning!"

In that case, wouldn't she have no choice but to let him leave?

No matter how jealous, how possessive, or how much she longed for him—she didn't want to exchange the gentleness that Tenkuji Yu showed her for her own willfulness.

The gentler he is, the less he wants to let her down; the more he fears that one day, he will exhaust all his gentleness.

Simply put, he spoils his younger sister to this extent that even the most domineering Kasugano Sora would feel embarrassed.

"Sorry, I'll bring dessert when I come back."

Yuu Tenkuji stood up and began clearing the dishes from the table.

As Kasugano Sora put down the rabbit she was helping, she casually asked, "Is that transfer student pretty?"

"It's not a matter of whether she's pretty or not..."

"Ok?"

"...It is quite beautiful."

Yuu Tenkuji never lies to Sora Kasugano; it's a rule he sets for himself.

Kasugano Sora's expression didn't change, as if she had been mentally prepared for this all along: "That's true, you wouldn't care so much about someone who isn't pretty, and you even went over to take care of her."

"What do you take me for? Do you think I'm that kind of person?" Feeling insulted, Tenkuji Yu said with a hint of annoyance.

Kasugano Sora completely ignored his feigned anger and continued to ask, "According to what you just said, there's no one at her house, or maybe she lives alone? Even so, she still invited you to her house and let you take care of her without any suspicion... Heh."

For some reason, the petite girl let out a cold laugh, her laughter as clear and icy as ice.

—Just like Yui Yuigahama, when it comes to questions about men and women, these girls' minds become even sharper than Sherlock Holmes'.

Yes, it's just simple reasoning, my friend.

Yuu Tenkuji simply gave up resisting and honestly admitted, "That's right, that's right, that guy really likes me. He probably called me over to try and seduce me, right? I know it's all a trick."

"You knew all along, yet you still went?" Kasugano Sora's gaze sharpened as she looked at his profile, enunciating each word clearly, "Although I know Yu isn't that kind of person, you wouldn't be planning to go along with it..."

"Don't even mention a boat, you can't even push a person properly."

Interrupting her, Yuu Tenkuji carried the bowls and chopsticks into the kitchen, speaking openly and honestly without a trace of guilt.

"Don't worry about it so much. I'm just going to visit someone in the hospital. I don't intend to take this opportunity to step onto the adult stage... Even if I did, it would be after I officially have a girlfriend."

"..."

As if she had nothing more to say, Kasugano Sora fell silent.

She didn't offer any further comments until he went back to his room to prepare and walked towards the entrance with his bag. She just silently watched his back.

"Then I'm going out."

Before closing the door, Yuu Tenkuji finally heard her weak voice.

"...So, Yu, would you like to date that transfer student?"

"Who knows? Maybe if she were more frank."

She stopped in her tracks and turned around.

Looking at the silver-haired girl standing in the shadows of the entryway, trembling as if she were afraid of being left alone at home, surrounded by loneliness, he said with a bright, sunny smile, "But even if we really date, if she doesn't let me go home to feed my sister, I'll break up with her on the spot! There's absolutely no room for discussion on that."

Kasugano Sora blinked blankly for a moment, then burst out laughing as if she couldn't help but chuckle.

"Ha ha……"

Just as the dark clouds in the gray sky gradually dispersed, and the distant blue stretched into the distance, the smile was so clear and warm.

"You idiot, Yu, don't make me sound like a cat, okay?"

"Meow~"

The real cat sat down at her feet and watched the boy standing in front of the door with her.

“I know, Yu is mine, and no one can take her away…” Kasugano Sora murmured, turning around and waving her hand casually. “Remember to come back on time for lunch, or I’ll get angry if you’re too late.”

"Okay, I'll be right back."

With a smile, Yuu Tenkuji closed the door and sighed softly at the street outside.

Unfortunately, she forgot the way she proudly said during her first mission, "You can introduce your girlfriend to me whenever you want, but I can't guarantee that you won't break up after she meets me."

If you still remember, things are probably much easier now, right?

Although some might consider him a scumbag who changed girlfriends three times in just two months...

No matter how the timeline changes, he has to get past his sister before he can get a girlfriend.

"Before this mission ends and the next one begins, I should have a good talk with her about this. Otherwise, we'll just be repeating the same things every time..."

Putting the problem aside for the time being, Yuu Tenkuji took out her phone as she walked towards the station.

"I'll make you some porridge. Do you have any ingredients at home?"

"We have a whole bunch of muscat and peach flavored ones."

"Sorry, my cooking skills aren't good enough to make porridge with nutritious jelly."

"Then I'll have to trouble you. I'm in so much pain right now, I just want to rub against you, please come and warm me up."

"Rubbing against it is unnecessary."

"That's actually the important thing, okay? Oh, and if you're going to the supermarket, could you buy me a box of cherries while you're at it?"

"This is truly the first time I've ever brought cherries when visiting someone in the hospital."

"I don't really want to eat it, I'm just bored and want to 'rerorero' a bit."

"Okay, whatever makes you happy."

Putting away his phone, Yuu Tenkuji shook his head, unsure whether to laugh or feel helpless.

...Conversations with Natsukawa Masuzu are never serious.

However, it is quite interesting.

Soon, Yuu Tenkuji boarded the train and headed towards the apartment where Masuzu Natsukawa lived.

He stopped at the supermarket on the way to buy the ingredients for making porridge before arriving at the luxury apartment building. Instead of pressing the intercom for the corresponding apartment number, he directly called Natsukawa Masaki.

"I've arrived, open the door for me."

"..."

There was no echo from the microphone, but after a short while, the automatic glass door slowly opened, and he stepped inside.
