Taeyeon Is a famous, but stubborn girl. She goes solo and is following her dreams. She's still in training, and because of her 'laziness' as they say and her stubborness, she has gone through many teachers and trainers.

But what would happen if a new trainer comes along and doesn't get off her back or gives into her stubborness. Even if he does, he leaves harsh comments with her, and leave without a second thought.

Aside from that, theres something he doesn't know, Taeyeon has heart problems.
