Fairplay:
Both has romance as one of the main themes & that doesn't really attract me anymore... (but I did enjoyed Weightlifting Fairy bc it isn't cheesy, but still pretty ave.). Still, really thanks!!
oh yeah, you didn't want any romance. I was so focused on "Non generic, great plot, not just serious (mixed w/ funny moments)" Here are some thoughts on each of these for you to think about before ruling them out. First, they are both not cheesy. I too don't like cheesy. Both are now in my top 10 because of the story.
Fated to Love You - an accidental pairing of the two leads ends up forcing them together, but most of the story is about the repercussions of them having to get married. They don't care for each other for most of the show. Eventually, one of them does fold and likes the other, but late in the story. Otherwise, its more of a funny, touching, sad, emotional story and then some romance. I'd actually still give this one a shot.
Oh My Venus - is really about the transformation process of someone who attempts to go thru a major weightloss. Its inspirational, really funny, identifiable. The famous personal trainer who ends up taking her on as a pupil accidentally eventually falls for her. He is a stoic, cold, humorless guy that starts to peel his own onion layers. Eventually there is romance in it, but that's not the driving line for the story persay. Once the romance part begins about 2/3's way thru the show, there are some love scenes for a short while, but that goes to the back burner until the end. This one probably won't work for you but I thought I'd draw out the plot as much as I could without being spoilerish.
