I really like Myungsoo (Hyungsik), Young Do (Kim Woobin) and Bona's (Krystal) friendship here, although in episode 8 (I think) Young Do and Bona had a little fight but I think they're okay now in episode 10.

Young Do (Kim Woobin) : She's the only girl that can be so clingy yet still be charming and pretty.

why are you so pretty?
