You're an orphan. You live by yourselves without the love and care from parents.

But since you met Rin, everything changed. When you were little, you helped a boy the same as your age which is Rin. You treat his wounds and he asked you to accompany him to his house. That's when you met Rin's parents, he also had a brother which is Sae. Since then, his parents are taking care of you and giving you love and affection you've never feel before.

Now, you both are in highschool. Rin was quite affectionate and clingy towards you. Hugging you from behind, lean his head on your shoulder, pinch your cheeks and even kiss your hand. He also get jealous easily.His clinginess towards you made your friends quite jealous. They always told you that he like you, but you only consider Rin as a brother.

The truth is they're right. He do has feelings for you, even if you didn't notice it.

Right now, Rin's hugging you from behind, watching you playing games on the tv.
