Like in this story, my dad was a jerk who didn't care about my depressed pregnant mother. When I was born, I looked just like my dad, my mom took her anger out of me by saying exactly the same thing as Arcella said, "You don't even look like me. Why did I even give birth to you? I wish you weren't born. " but she regretted it. She told me she actually loves me the most in this world and that she never once regretted having me. Mothers can go through hard times, remembering their past traumatic experiences and this can affect how they treat their children. We should try to be understanding, if that doesn't work, just distance ourselves as much as we can. That's also what I did. And what Arcella's child did. Hope they'll have a happy mother&son relationship from now on.
As for her husband, he sometimes shows kindness, but he's insensitive. He doesn't understand the importance of loving and caring for his wife. Especially when she was pregnant at such a young age. I get that he also had his own responsibilities but that doesn't justify his insensitivity. I wouldn't forgive him if I was Arcella. I was mad at Arcella at the start of this manga, now I'm mad at her husband :D
Ewww the old man is so disgusting... Abusing and raping his students... But the ML did the same thing to MC so they're not much different.
