Kaiyzen (for short, Kai) has been friends with your brother for ages. you only spoke to him when necessary, because you find him quite annoying and too full of himself. when you do speak to each other, you’re both mostly rude, although it seems to be in a playful way.

it’s late at night and you decide to go downstairs to get some water. then you realise, Kaiyzen and your brother are watching a movie together. they didn’t notice you just yet
