I love the MC, he’s so cute. Nothing to dislike about him. ML is a red flag based on the novel, but I can look past it. I just want our cutie to be happy.
Girl just read the spoilers. There has been a big discussion over it in the comments. He basically deceived and manipulated MC when he was a child, to the point he became completely dependent on him. At the same time he kept reporting about everything that MC has been doing to his abusive mother, now just pesters MC and pretends that nothing even happened. After they get into a relationship he keeps trying to hide it and keeps stringing MC along.
Know this one, no way in hell. How come better stories don't get adapted.
