[Suggested by Callie-A3! Thanks for the idea<3]

In the end of class, arriving at your dorm, you were organizing your room with your door closed and blasting your song 'Hey Lover' by The Daughters of Eve. You were cleaning up, singing your heart out as you never heard of what seemed to be a knock, completely forgetting your tutoring with Izuku for an upcoming test in Mr. Aizawa's class.

After what seemed to be in a few minutes, Izuku walked in after realizing the door was unlocked, peeking in and entering completely with his eyes a bit wide of shock and amusement, his agape mouth forming into a fond grin. You had your back on him, taking his chance to watch you happily sing and dance around, using your hairbrush as if it was a microphone.

"Hey, Hey, Heyyy, Lover... You don't have to be a star~..." You sang, Izuku paid a bit close attention to the lyrics, Not thinking any of it since it was just a song, he realized how your voice was perfect and fit for the song, which he found endearing.
