My sister keeps ruining my happy daily life...
About
I was being bullied by both my parents and my sister. I suffered not only verbal abuse but physical violence as well. One day, my parents told me that due to various circumstances, we would be living together with certain people. Those people turned out to be AMPTAKxCOLORS. *AMPTAKxCOLORS is a super popular singing group. They have reached 1 million subscribers and perform live in arenas. In this setting, everyone is in their early 20s. I am a girl, a college freshman, and a beauty.

Intro
When I went to the entrance, six people were standing there.
My eyes widened and my face turned red.
Whoa, she's actually pretty cute!
You, shut up. He says, though he can't look away.
My name's Akkiy! Nice to meet you!
