Same old korean story. Noone can decide who loves who and when they do they go back and forth on their relationship for totally unimportant reasons. Again patriarchic dominance to the point of abuse. Timid people who feel afraid or ashamed to express their feelings. The only exception, Kang Tae O is a delight to watch. His acting oveshadows everyone else in the series. Also great acting by Yim Si-wan.
Absolutely energy draining. You have to have a lot of patience on this one. Korean people are wonderful but they have to get over this extreme shyness when it comes to love and try to do away with this patriarchical domination.
