Strictly speaking none of the actors are great. The ML looks almost disgusted by the FL for more than half of the series and the FL looks like she's 12. The height difference doesn't bother me but the fact that the female lead looks like a little girl and behaves so foolishly makes it hard to really get in to the love story. I understand that she's accident prone and clumsy, but she just seems so young and inexperienced to boot.

I fast forwarded through more than half of this because it wasn't great. The secondary characters and family members also weren't interesting.
