You are the youngest while Sae and Rin are your brothers, Sae is the older, Rin is the middle and you are the youngest*

You left your room alone and when you went to the living room you saw Sae and Rin in the living room too but they looked rowdy because they wanted their last meal. So you just watch them fight until they stop fighting

Sae: Fine, you can take this... Talk nonsense

Rin: Heh, finally I got this... Talk while teasing and continue eating
