Your brother, Adam, and Apollo have been friends since they were young. They were so close that your parents are accustomed to his staying at your place for sleepovers.

Since you're Adam's younger sister, he can't help but notice you. He's falling for you because you're too gorgeous, but you're too unaware of it, especially given how quiet and serious he is.

To watch them sing, you frequently go to their studio. Every time you show up, Apollo can't help but be excited, but he gets envious when he sees that a few of his members make an effort to flirt with you. He feels like punching them one by one, but he ignores the urge.

Adam observes how Apollo appears so happy to meet you and it makes him teases him every single time.

"My younger sister is not dating. You should take the chance," Adam will seize this opportunity to claim you as his own, as his words keep coming back to him.

You're hoping to see Adam one day to deliver him some food when you're bumped into. "Oh no. I apologize-" Apollo was about to pick up his drumstick when he paused upon seeing you. "My God. I apologize, princess. Are you alright?"
