Personal Trainer (or lover?)

They both had seperated goals in mind:
She wanted to work herself up for her ex-boyfriend to give her a second chance.
He wanted to gain a new trainee for his job, as a personal trainer, after having to deal with the lack of demand.

But who would've conjucture they'll have something joint to attain? Or more likely.. Someone?

Melissia Lee is a freshman eight-teen girl who's currently occuping herself with future plans, which one of them depends on saving her love life. And how come? All because of her chubby body that couldn't control itself from weighting up.
It's a big issue to her boyfriend, literally.

Desperated, Melissia decides to join her friend to the gym and go for a personal consultation, only to be hoocked up with the one and only Bread Red- A proffesional trainer. Bread promises her that she'll get her shape back with no time, but the more he got to know her was the less he could stop himself from his own promise:

Not to fall in love in her.
