Nah. Not only that. I think his attitude and threatment of Haesoo is bc as far as he knows and have seen prior their divorce: she literally has no one too. No family, friends and she changes job often enough to not bond enough with her coworkers. And objectively speaking being on a friendly terms with your colleagues rarely guarantees to that they offer you a stay at their house and help you out. + She doesn't seem to open up about her financial and private life issues for obvious reasons easily.
Just like you said he made so much sacrifices for her sake so there's a heavy guilt and feeling of being indebted to him somehow bc she is lead to believe by him and his friend that she ruined his life. he got into debts and loans to save her life I think when they lost their kid so yeah. In his eyes, he's her only support. + there's this delusion of his that no one will ever like her because of how she dress and her passive personality.
Luckily Taeha has been amazing at distracting her with his advances so she doesn't have time to think of him. I only wish she burnt his stuff or changed the locks (which Ik wouldn't easy given the house is other his name if I'm not wrong????)
Okay we all make mistakes when we're young,especially when there is no close one to guide.But Mincheol you can't blame Haesoo for that,it was your own damn choice!
Did he actually develop that superiority complex bcs of subconscious regret that "oh Haesoo I,the boy many girls ran after,I sacrificed my could've been Good Life to be with you,for you,so don't you dare leave me,you can't leave me,No one will choose you" （￣へ￣）
Mincheol,I don't know what to feel anymore,do i hate you,or do i pity you,for being so miserable.
