After a while, Kato Yusuke sat next to Shiyu with two cups of coffee.

They found a movie and passed the time casually.

Shiyu cuddled up against him, her head resting on his shoulder, and there was a glimmer of light in her eyes.

She used to lean against the pillow, but now she has a human pillow with its own temperature, which can adjust its angle according to her movements and postures, as if it were tailor-made.

After watching a movie, it was already 11:30 pm.

Considering tomorrow's things, it's almost time to go to sleep.

Shiyu entered the bathroom again, stood in front of the sink mirror, and found that her face was so red that it looked like she had drunk alcohol.

She chuckled, took a deep breath, turned on the faucet, wetted her toothbrush, applied toothpaste to brush her teeth, and finally poured cold water on her face.

"Yu-chan, I've finished washing up, you can go brush your teeth."

"okay."

Back in the living room, the layout of the room has changed.

The original low table was moved to the corner and replaced by a set of quilts spread out on the floor, about ten centimeters away from the bed.

"Pedant……"

Shiyu grumbled and sat down on the bed, unbuttoned his shirt, took off his trousers, and got into bed.

There is a man's scent on the quilt.

There is a light fragrance of laundry detergent floating outside, but there is a bit of a rough smell inside, exuding a slight mint coolness from the owner's body, like the grass after a new rain.

She smelled it intoxicatedly, couldn't help but close her legs, and her cheeks felt slightly hot.

At this time...

"Senior Shiyu."

Faster than expected, the boy returned to the room.

"If you're ready, can I turn off the lights?"

"...!"

Shiyu got his head out of the quilt, replied with a good word, and asked another question when he turned off the light and walked to the floor.

"...Yu-chan, are you going to sleep there?"

"You can tell this kind of thing at a glance, right?"

"...There should be other options, right?"

"Otherwise we have to exchange?"

"Cold-blooded man..."

Kato Yusuke shrugged and remained silent.

"...I don't really want to sleep yet."

As Shiyu spoke, he moved to the inside, stretched out a hand from the quilt, and patted the mattress, "Lie down here and chat with me."

"Hmm? I can also chat with you down below, right?"

"But I want you to hold me until I fall asleep..."

After a brief silence, a feeble sigh sounded in the darkness.

"That kind of thing...even a primary school student wouldn't do it, right?"

"Oh? "Today is Shiyu-senpai's birthday. No matter what, I will try my best to satisfy you." Why do I remember hearing such words just now?"

As if surprised by her imitation, Kato Yusuke opened his eyes wide in surprise.

"...Honestly, wouldn't it be a bit disgusting if you imitate the male tone too?"

"Kato Yusuke!"

Shiyu's eyes were as sharp as ice in an instant, and he uttered two words concisely: "Come up!"

"Yes, your majesty!"

Kato Yusuke's body was shaken, and he reluctantly came to the bed and sat down, folded his hands on his abdomen, and lay on his back staring like a zombie.

...Look, he always appears to be submissive at times like this, but in fact...

"...Yu-chan, come over here."

"No need, I'm just fine."

"I told you to turn around."

Shiyu pulled his face in displeasure and forced him to turn to her side.

In the dim environment, the distance between the two heads is extremely small.

Their breaths froze at the same time.

An unspeakable silence filled the space between the two.

Shiyu observed him intently and finally smiled.

"I always feel like it's like living together..."

As if trying to convey something vaguely, Kato Yusuke laughed: "Maybe..."

Amid the faint rustling of the wind, his voice was slightly deep, which was very nice to hear.

Shiyu nudged towards him and asked softly: "Aren't you going to hug me?"

Kato Yusuke turned around completely, his voice was a little depressed: "...Do you know what that means?"

"It's not like we haven't hugged each other before."

Shiyu said in a funny voice, and then changed into a sarcastic tone.

"Besides, you seem to have hugged and carried Sawamura-san several times, right?"

"The meaning is different."

"What's different~?"

Kato Yusuke narrowed his eyes slightly and said: "...She is not my girlfriend, but my senior sister is."

Shiyu was taken aback, then showed a mixture of joy and sadness, and said: "...I will definitely never forget this sentence."

After a few breaths, the boy gently hugged her through the quilt.

"Thank you, Senior Shiyu."

"for what?"

"Um...thank you for staying in a desolate ruins?"

"ruins……"

Shiyu breathed a sigh of relief, gently held the face of the person in front of him with both hands, and spoke like a murmur.

"But the ruins in your eyes are actually the castle in my mind."

A soft voice floated into his ears, and Kato Yusuke was suddenly stunned and speechless for a moment.

"Senior Shiyu..."

"Then, there lived in that castle a passionate prince and his six princesses, as well as a lover from a neighboring country?"

"--Well?"

"Haha, you seemed a little touched just now~?"

"...Now that you know, can you return my emotion?"

Shiyu pinched his cheek proudly and pretended to be angry: "A philandering scumbag has no right to make demands."

"I'm sorry, what you said is extremely..."

"Speaking of which, do you want to come to my house during the next Chinese New Year?"

"What……?"

Kato Yusuke rubbed his cheek in pain, looking confused.

Shiyu continued speaking calmly.

"Then we can go to the shrine together for New Year's worship. If you want, you can bring Xiao Xi with you."

"...No, you can't say that kind of thing no matter what, right?"

"If you plan to go back to your hometown in Saitama for the New Year, I can also go back with you. To be honest, I miss Aunt Mina a little~"

"Isn't that even worse?"

Kato Yusuke said extremely speechlessly, which made Shiyu a little unhappy.

"Why? You're already celebrating the New Year at Sawamura's house, but you still refuse to come to my house? Otherwise, if I give in a little further, you can bring Shinjou-san with you."
