With my romance comic, both start off as childhood friends, training alongside one another in taekwondo, where the girl has always loved the boy, waiting on him to make the first move, but then the boy leaves suddenly, travels overseas for personal reasons and finds someone else. The girl eventually becomes a fashion model, while the boy makes a name for himself in the world of martial arts. The boy comes back, out of nowhere, as he believes the girl has intentionally reprised her role as a taekwondo practitioner, but her greedy new boss has decided to combine her talent in martial arts with her modeling career and now is stuck with something she had no intention of participating in ever again: tournaments. The girl and boy are strong-willed and successful in their endeavors, but when it comes to love, neither still have much experience.
There's a LOT for the girl to consider, but for the boy (now a man) it is through taekwondo, in his support of her in this martial art, that he starts to come to terms with his true feelings for the girl.
