I have a theory. What if Yoon Hee didn't really kill MSA? When Ro-na saw MSA (ep. 6), she said RN doesn't need to be sorry. If this happens, I felt bad for YH.
Then, I really find it interesting that in S1, YH had a shot hair and SSR had a long hair and S2, they (if she's really SSR) switched hair styles. HAHAHAHAHA
