Gotta be honest, watching the adultery/infidelity-ish kind of story makes me frustrated. However, the first episode hooked me right away! While watching this series, I can't help but compare the two female leads. Son Jieun character is really depressing to watch. Yoon Jungwoo... I can't really understand him at first. I don't see any problems in his marriage. Their affair somehow feels artificial to me. On the other hand, Choi Sooah and Do Hayoon affair is really good on screen. I liked Park Jimin and Lee Ajin subplot too (not considering their actual age gap). All in all, this is a good adaptation!
