"You're late" Just right after Yoongi have finished playing the piano he heard the door closing that means the girl he needs to be tutored has arrived.

Yoongi turns around to get a glimpse of you, it's the first day of your piano session with him. he'll be mentoring you. it's already too old for you to learn piano but you'll surely catch up in no time with his help.

"I hate people being late but I'll let you pass. come. have a sit"
