Where Jimin is an adorable teen who doesn't know much about the "adult" things whereas Yoongi is a mischievous not-so-innocent person.
Yoongi accidentally texts Jimin thinking it's someone else. But he sticks around in hopes of getting into the "innocent" heart and maybe finding true love. Jimin on the other hand is completely oblivious to Yoongi's flirts and thinks that the others text are just him being nice. They become buddies through text messages until Yoongi becomes a music teacher in Jimin's school.
