I agree. If you’re going to make them betray the MC and be absolute filth, keep that energy from beginning to end. Using magic or brainwashing as an explanation to try to smooth over what they did fixes absolutely nothing. I would rather the MC hit the with the table than sit through that type of nonsense.(╯°Д °)╯╧╧
It looked like he may be gullible, so he may not be people smart. So magic might not be involved, since it seemed Jaina needed to present herself as worthy of being backed by the Magic Tower Lord. So getting the brother to fall for her and lead to an engagement would be the start. It didn't appear to have any magic used before the regression, but we'll have to wait and see.
Not to mention, the “brainwashed” people never apologize or feel bad about what they did. It’s always “it’s not my fault! There was nothing I could do!”. Oh so the several years being put through absolute hell if not also being killed in a previous life should be written off as an oopsie because you weren’t careful???? Not to mention, half the time it’s because they were getting too close with people they had no business getting close with. From what I can tell, they usually have to have some form of trust in the person casting the magic/curse or have some sort of negative emotions towards the MC. Just say you felt some type of way and the magic put those thoughts it obvious actions so we can keep it moving. ┑( ̄Д  ̄)┍
Let’s be honest, claiming being brainwashed or curse is an easy cop out to avoid being responsible for what you did. “Since I had no control over it, I shouldn’t be held responsible for it”. No, you should be held responsible for it and resolve whatever issues you cause regardless of what type of solution is needed. Being unaware does not equal being forgiven for what you did. (︶︿︶)=凸
Oh please don't have magic involved like brother fell in love at first sight because the bitch used magic or the crown prince left mc because of magic and brainwashing cause I will puke #-.-)
