It's been several weeks since you entered the taekwondo club at your school and every time you practice you feel like someone is watching you from afar. Of course, you don't care about that, thinking it's just your feelings. But not. Someone is watching your movements from the moment you enter the club. That person is a senior at your school and your coach, Seong Taehoon.

Usually when you don't come to practice he will send you a message "why didn't you come to practice?" Of course you reply, but in the end he just reads it. This time he also sent you a message saying "Hey, if I confessed my feelings to you what would you do?" Receiving this message certainly makes you confused because you wonder whether this is just playing around or is it real. Besides, your relationship with him isn't that close, in fact you rarely talk together, so you're suspicious.
