So, this series is fine but story-wise, ummm let me think of it for awhile. For acting, I'm surprised how passive and submissive Mild is. I thought that his character's personality in the series will be developed but nothing had happened. His partner in the series portrayed his roles quiet good. The rest of the cast were a bunch of nonsense. The title did not obviously fit to what the series all about. If "The Best Twins" is really it's title, it should focus on the two lead twin here but it's more focused on Mild and the other one. I'm really turned off to the homophobic sister and the obsessed ex in the series. They are really getting into my nerves. I hate these characters and some actors played their roles awkwardly and subpar. Anyway the only soundtrack it has for the series is good, I like it (honestly there were times when I heard this song in my head continuously playing hahahaaha). Pak did really have a chemistry with Mild's character's sister for me. After all, this series is fine but subpar.
