Oh boy you don't deserve her , she deserves better than that .. at least talk to her and try to understand her , she was your friend wasn't she ? It's sad that you're treating her like a monster and not you being disgusted by the fact that a mermaid kissed you so all this time you never viewed her as an equal? You just saw her as monster that can act as your friend whenever you need to
He was a kid befriending another kid. Then the MC saw his old friend again but she killed the aunt and uncle. Even if they deserved it. You would fear a murderer too - that's not seeing someone as not equal. That's fear. And now he is on a turning point of being so scared for even rain that he is thinking of killing her since that's the only way for him to escape.
I like both couples , they're both wholesome and involved in each other lives
