My love index is at its maximum.

Ever since Tsukasa Tazaki appeared, the Navy seems to have changed its dogs, and it feels like they despise them more and more.

Has it already defected to the enemy?

Thinking about it this way, Hoshino Shikami was suddenly overcome with sorrow, and her lips trembled involuntarily: "Navy, I raised you~"

In her sorrowful voice, one could faintly hear the heartache and helplessness of an elderly mother watching her son embark on a path of crime.

Tsukasa Tazaki walked onto the porch and reached out to rub his sister's head like a sailor would.

"Snapped"

Hoshino Shikami slapped his hand away: "We're not familiar with each other!"

"Where did the number ninety-nine come from?"

"..."

Do you still want to stay in Tokyo?

The sister-in-law once again lost the will to resist and obediently let her brother-in-law pat her head.

"Lu Jian is so good."

Tazaki Tsukasa rubbed his hands several times with satisfaction before changing his shoes and going inside.

The sister-in-law followed behind her brother-in-law with her head down, her beautiful face flushed red, whether from shame or from the pleasure of being stroked.

The air conditioner was on full blast in the living room, and you could feel a cool breeze on your face as soon as you entered.

Hoshino Hanami was tapping away on the keyboard of her laptop on the sofa.

She wore a pristine white loungewear dress, her hair cascading down her back, her bangs secured to her left forehead with a deer-shaped hair clip. Her smooth legs were casually draped over the coffee table in front of the sofa, her bare calves revealing smooth, glossy skin and subtly muscular lines that exuded a healthy and carefree charm.

As Tazaki Tsukasa walked and looked around, he suddenly turned to his sister-in-law and asked, "Aren't your legs pretty, sister?"

"Mmm!" Hoshino Shikami nodded vigorously.

Do you like it?

"I love it so much, I wish I could hug my sister every day!"

Tazaki Tsukasa smiled smugly: "It's no use liking her, my sister is mine now."

"..."

Hoshino Shika's face suddenly turned green: "Tazaki Tsukasa, I'll beat you to death!"

"Hey, don't hit me in the face!"

Hoshino Hanami looked up and saw her younger sister throwing a punch at her boyfriend's face with a look of disgust. The way she looked was so childish and funny that she couldn't help but laugh.

"You two, stop fooling around and come sit down!"

Her older sister beckoned for Tazaki Tsukasa to sit on the sofa next to her. The white lace curtains were drawn on the glass windows facing the courtyard, and the midday summer sun shone brightly, making her appear dreamlike and beautiful.

"What are you doing?" Tsukasa Tazaki asked her, but his gaze went straight to her feet which were resting on the coffee table.

The ten toes, painted with light pink nail polish, were slightly curled together, looking as adorable as a tired dog resting in the park's water fountain after a walk. Beside them sat a vase with three white lilies in full bloom, their delicate fragrance wafting through the air.

"Help Lu Jian with his physics homework."

Hoshino Hanami stared at the screen for a while, then seemed to give up and turned to Tazaki Tsukasa, pleadingly saying, "Flame reaction and all that, I really don't understand as a humanities student. Tazaki-nii, can you help Hanami-neechan?"

Tazaki Tsukasa smiled faintly, deliberately raising his eyebrows a few times: "That depends on whether Hanami-neechan is sincere."

"You can stay overnight tonight."

"No taking it back!" Tsukasa Tazaki's eyes lit up instantly.

Hoshino Hanami leaned back and gently rested her head on his shoulder: "Big sister will take good care of you and make sure you're lively and happy."

"..." Ignored, Hoshino Shikami pouted and tugged at her sister's clothes with a wronged expression: "This is my homework, I don't want my sister to ask him for help!"

"Lu Jian is right."

Hoshino Hanami rested her chin on her hand, looking at her younger sister with a smile: "Then you should ask your brother-in-law yourself."

"Eh? No, I..."

"No need to say anything more, you must follow your brother-in-law's instructions in everything you do today!"

?

Am I no longer your biological sister?

Hoshino Shikami stared, mouth agape, trying to find the right words to express her shock.

But after staring blankly for a while, she still couldn't find it.

During this time, Hoshino Hanami got up and went to the refrigerator to get a large tub of ice cream, which she ate while watching the show. Tazaki Tsukasa, sandwiched between the two, looked at his homework for a while, then put on a serious, elder-like face and began to exercise his power to control his sister-in-law.

"First, please answer a question for your brother-in-law, Deer: Why do fireworks have colors?"

"because……"

Hoshino Shikami frowned and thought for a moment, then chewed on her hand in a daze: "Did they add paint when making the fireworks?"

"Incorrect! The correct answer is that a physical change called 'flame color reaction' occurs when fireworks explode."

"not understand."

Hoshino Shikami felt that the more she chewed on her hands, the more fragrant they became, much more so than any physical change.

"The so-called flame test is when salts of alkali metals, alkaline earth metals, and copper are placed in a fire, causing the metal elements to produce a unique color reaction."

"What does this have to do with fireworks?"

"In the process of making fireworks, metal salts of corresponding colors are added to black powder. After the black powder explodes in the air, it will produce an open flame. At this time, the metal elements will produce specific colors according to the corresponding spectrum."

Hoshino Shikami gave her a dismissive look: "Of course I know something this simple!"

"Why didn't you say anything when I went with you to the summer festival fireworks display before?" Hoshino Hanami asked while eating ice cream. Tazaki Tsukasa turned to look at her, and she casually scooped up a spoonful and fed it to her boyfriend.

"I just didn't want to ruin the atmosphere!" Hoshino Shikami thought for a moment, biting her hand, then sat down next to her sister, tilting her chin slightly and blinking her eyes cutely: "As long as my sister is by my side, Shikami's world will always be full of color, so there's no need for any flame reaction."

"whispering sound……"

Hoshino Hanami was too lazy to pay attention to her sister's fangirl-like behavior, after all, her scatterbrained nature wasn't a new thing.

After a moment of silence on the sofa, the younger sister snuggled closer to her older sister: "Lu Jian wants to eat ice cream too."

The older sister moved closer to her brother-in-law: "There's some in the fridge."

"We should feed the deer too!" The younger sister shamelessly leaned closer again.

Hoshino Hanami smiled irritably and said, "This spoon has your brother-in-law's saliva on it, so it's impossible to feed you anymore. Go get it from the refrigerator yourself."

As she spoke, she reached out and pinched her younger sister's cheek: "You're almost sixteen now, why do you still act like you did when you were little, always trying to mess around whenever you see your older sister?"

"It's just that my sister is too charming."

Hoshino Shikami shamelessly moved closer, grabbing her older sister's arm and acting coquettishly: "Shikami is so cute, you definitely wouldn't bear to leave her alone, right?"

"Yes, that's right."

“Of course!” Hoshino Hanami nodded, then a charming smile appeared on her lips: “On the day my sister and Tazaki get married, I’ll have Shika be her bridesmaid!”

?

Hoshino Shikami asked blankly, "...Bridegroom?"

"if not?"

Hoshino Hanami narrowed her eyes, her lips twisting slightly to one side as if in a mischievous way: "Does Shikami want to be a bride with my sister?"

"Is there really such a good thing?" Tsukasa Tazaki was immediately delighted. As if joining in the fun, he reached out and put his arm around his older sister's waist: "The most beautiful Hoshino sisters in the world, this brat wants them both!"

Hoshino Hanami turned to look at him, and their eyes met for a long time with deep affection.

then.

Slap it.

The older sister raised her hand and slapped her little brother, shattering his dream into pieces.

Hoshino Shikami bit her hand in a daze.

Meanwhile, I was also thinking to myself whether the suggestion of being a bride with my sister was a way to never leave her.

Around 2 p.m., the two sisters went back to their rooms to take a nap.

Tsukasa Tazaki hadn't had lunch yet, so he went into the kitchen to make something to eat.

I took orange juice from the refrigerator, drank it while putting slices of toast in the oven, and sliced ​​half a can of sausages, heating it in a frying pan. From the kitchen window, I could see the tall oak trees in the yard, with a cool breeze constantly blowing in, and three plump crows, seeking refuge from the heat, perched motionless in the deep shade of the trees.

After eating sausage and toast, Tsukasa Tazaki drank two glasses of water in one go. He thought to himself that summer should have its own charm, and there was still so much time before dark, so how could he let it go to waste?

So he slipped straight into Da Ke'er's room.

Hoshino Hanami sprawled on the beanbag chair by the window, a tablet in her hand. Looking out the window behind her, the sky was vast and the outlines of the clouds were exceptionally clear.

The weather is so nice...

Tazaki Tsukasa walked in cheerfully, squatted down beside her, and looked at the tablet screen, which displayed tourist information about the Izu Peninsula.

"Why are you looking at this?" he asked curiously. "Are you planning to go to Izu to escape the summer heat?"

"Yes, that's right."

Hoshino Hanami swiped her finger across the screen, browsing the information: "Didn't you say you wanted to go to the beach in Minami-Izu last time? I want to go too, especially if I can go with you."

The afternoon sunlight streaming into the room gently enveloped her body, and perhaps because of her cheerful mood, she seemed to radiate vitality even in her fingertips.

Tsukasa Tazaki caught a ray of sunlight in his hand and gently pressed it against her cheek.

"What's wrong?" she asked, tilting her head.

I like it this way.

“I like it this way…” Hoshino Hanami repeated, then chuckled, “I like it this way too.”

Tsukasa Tazaki brushed her hair aside with his fingers and kissed her ear.

Her supple body and the fragrance of her hair blended together naturally, making people feel warm and comfortable.

Time passed slowly between the two of them, like a gentle breeze.

After a while, Hoshino Hana turned her head away as if ticklish, smiled and put the tablet aside. Then she opened her arms and said sweetly, "Aren't you going to carry Big Sister to bed?"
