Yes, her points make sense but they over look the reasons why seme is such a “bad” adult. Just because a person is an adult doesn’t mean they will behave like a model one.
I think seme is definetly traumatised and the reaction of the wife doesn’t take into consideration his trauma. I kinda see myself in the seme even though we don’t know his full story because people around me always throw the same words at me when I “fail” as an adult. Ideally we should be like that, realistically it means nothing because most people aren’t “perfect adults”.
We have yet to know what Minyoung did but I think the main perpetrator of seme’s trauma and failed is his dad

I understand that the ex wife have a point, but it's looking quite an aggressive approach rather than trying to see in his POV.
His fear, his avoidance, have reason, though can't fault that her words are valid (ngl I do think her anger is valid if their f up relationship had gone for 10 years with no improvement). She looked like she lost her shi* due to unable to "control" her husband. They seems like a seriously incompatible couple ┑( ̄Д  ̄)┍ smhw glad they divorced instead of hurting each other even further.
Well tho, it seems Cheol didn't tell her what happened in the past. Still, that aggressive verbal and all really sounds hurting. And not that hurting him can miraculously help him not avoiding things anymore. It seems he's been running away all his life because somehow "it's always his fault/he's the problem". This absurd toxic defense mechanism aaaa (╯°Д °)╯╧╧
