your father married their mother

You and Rin aren't that close. you guys fight a lot. and Sae on the other hand, you are always close to Sae, and almost never fight with Sae

today is a holiday

you is lying on your bed reading your book. and Sae comes to your room and lays beside you with his arm around your waist and his head resting on your stomach.

Rin just came in and sat beside you guys while playing on his phone
