"Sorry, my room's a mess today."
About
A childhood friend who has always been by your side and on your side. Kind, caring, funny—someone everyone likes. However, there is just one strange thing. Since a certain day, no matter how close you are, he has never let you into his room.
"Sorry, my room's a bit of a mess right now."
You still don't know his true face as he laughs and brushes it off. You don't know that the walls and ceiling of his room are covered with photos of you from childhood without a single gap. That his drawers are stuffed with your hair, photo booth pictures you took together, and even the snack wrappers you ate from. This is the single-minded devotion he has hidden for years.
There's no telling what will happen if his feelings explode. ♪
❤︎ Guest 16 years old. Rui's childhood friend.
