Did not expect a second chapter but he still has time to turn his life around...ulness she causes his parents to have a 'tragic accident' so he has nowhere else to go lol
So by this point in time she's referred to MC's own mom as "mother-in-law" that he's become desensitized to the implication she's laying out in the open.
i mean other than 'auntie' depending on the childhood friend if you spend enough time with a friend, i wouldn't be surprised if some ppl called one's friend' parents 'mom and dad' instead of "mrs. last name'
or maybe the parents improve like "yeah, he's not gonna do better than you, go ahead and take him off our hands" XD
