Down the list a ways but the spunky Yu Bi (Yoo) and stoic Pil Mo's (cap) characters were set up to be a very cute extra couple. Why did they not resolve them in any fashion? Such a no brainer and would have been the cherry on top of a decent drama. While I'm here not a lot of shipping moments at all for lead couple as well. Interesting story, low rewatch for me tho.
