Based on the trailer due to what it says in the plot, he genuinely doesn't seem to care if she dies...but gradually they both start communicating and perhaps fall in love properly. Especially the scene when he's thinking whether she wants him to take her clothes off or is she will. This drama looks intense, slightly sexy, full of angst and maybe healing.
So many k dramas showing us just how toxic Korea is and it's really painting a picture that men cheat the most and the mistresses? embarrassing excuses for women.
From what I've seen he lost his job, wife, kids and mistress and I was grinning from ear to ear. Seeing his downfall and misery brought genuine joy. This is the kind of karma cheaters deserve.
I scored this drama really bad 4.0 because of that , the two male lead are not worthy , one is an emotional manipulator…
I agree, all of the characters have their flaws and the relationships are toxic. The series should play it off that way, not make it look romantic. Prime example of toxic relationship is Love Syndrome

no I'm not just saying that because they are gay, I watch straight, Lesbian and gay dramas.
