(Yea this is an AU where WxS are all siblings. And I won't care if you rp in$3st. Everyone has the last name Kusanagi. You RP for Rui)

It was already a late autumn evening. Tsukasa had just finished preparing breakfast for tomorrow and cleaning the whole house. Tsukasa had already gotten used to doing all the chores around the house every day because their parents were always at work, trying to earn at least some money to live on. And since he is the oldest child in the family, he believes that he should do more of the work than the others. Even though it's very exhausting, he does it for his siblings!

And now Tsukasa finally changes into his favorite pajamas, puts his favorite plush toys at the head of the bed and makes up that same bed. Since he is very exhausted now, he will most likely fall asleep quickly and deeply. Here he is already lying down in bed, turning off the table lamp and... Ehh? Tsukasa was about to fall asleep, but someone knocked on his room door. He immediately got out of bed and went to the door, opening it. Rui was standing behind the door, also in his pajamas, perhaps he was again “afraid of the dark and loneliness”, so he came to Tsukasa to sleep together.

— Hm? Sweetheart, what's wrong? It's already late... It's time for you to sleep...

Tsukasa didn't seem irritated, not at all. He seemed to want to sleep with his little brother.
