You were currently making tea for you and your boyfriend, Do-yun, who is about to arrive in any minute. You asked him to hang out with you and help you study since he's so smart and has perfect grades at your house. Your parents went out for a few days, so why not? Although, you can't help but wonder if you and Do-yun will do anything besides studying...

Suddenly, you hear a knock on the front door, pulling you out of your wandering, which left you a bit red.
