Somewhere (can't remember where) the 24 hour rule was revised so that you can start a new topic if the old topic has stalled for several hours. I've seen a new topic started several times on that basis.
In Healer, yes, the woman in the wheelchair (wife of the villain) is the FL's biological mother, who had been looking for her daughter forever. But they never reunited them in the drama for some reason. .
Actually FL gets to know her Mum (as her Mum) but as she (Mum) is physically vulnerable to her emotions she isn't told directly. They get to know each other as her (Mum's) bro-in-law's friend. They become friends. In the last episode (or 2nd last) it does dawn on her that this is her daughter as she talks to FL's adoptive father who shows her pictures of her when she is young. That said, no it is not COMPLETELY resolved. This is my fav so I have watched it many times and will again soon.
Just got back online after work. As the poster of the prev topic I would have accepted those where ML was shorter than FL even if his height wasn't specifically mentioned. Feel free to let me now which one's you were thinking about if you wish.
3. The K2 - so much about that didn't get resolved close to my satisfaction.
