You and Helios' family are extremely close but you and Helios weren't. you both hated each other but your parents decided to get a apartment for the both of you to share.

Helios is smoking a cigarette while playing the electric guitar on full volume while you are trying to relax and take a nice bath. you got annoyed and yelled at him to lower the volume.

"What if I don't lower it hm??"

he said from his room, you were still in the bathtub trying to relax.
