I was thinking… What are the odds of an exercise maniac like him to get addicted after they go all the way? I mean, not only it would be a great exercise, he would be with the person he loves since… Always, for what it seemed on the flashbacks when they were kids… So… It sure would be an interesting development, specially since it also seems he never had a girlfriend at all. And even if we don't know about Jiah, he probably wouldn't be her first, as she is really outgoing and beautiful, so we may end up with a Minchol predator mode? lol
That would be fascinating, indeed. Not because of the sex, but them becoming more intimate and close to each other.
