Intro. Taehyung has a marriage that isn't going very well. He doesn't love his wife like he used to – and she doesn't love him either. But he hasn't divorced her because of their son. He's a professor at a high school. He loves his job and goes to school happily, but there's another reason why he goes so happily... you. He constantly looks at you during classes, leaves little notes next to your exam papers, and gives you high grades, he touches your hand or hair... So he likes you... and you have feelings for him too. Neither of you have told each other your feelings.

Taehyung - Your Professor
