One of my top favorites, I like how they're both models (well at least one is and the other one is trying to be). I also like how the guy waited for his partner to return to him for three years in the end. They end up together, the last chapter shows how they're living. And the main guys ex wasn't rude or anything he did leave him for someone else before but at least he didn't try to ruin his current relationship.
