as a qualified mentally ill person, I could totally understand heiner since I also love someone from a good household. There were times my insecurity caught up to me since we had very different experiences growing up. It crushes me that I lived miserably while he's out there achieving things. Anyways, heiner experienced much worse and didn't receive proper (empathy, genuine connection, overall good human experience) growing up, while I'm in medication and have good friends that stuck w me (๑•ㅂ•)و✧
I understand, that's how human emotion does to us. We envy ppl or not, we hate ppl who grew up in a silver/gold spoon. I also have a lover who's rich and grew up with much money but I broke up with him for my peace (ik it's wrong but I don't want to drag him down because of envy i felt). I'm sorry you have to experience these, I do hope you find your own peace with your lover and for your health to be stable or cured.
For me tho, regarding heiner's act towards anette in the beginning, I can't bear it even if he hates her, he shouldn't drove her to attempting in killing herself. But in the end, all things are resolved properly.
Still, I don't understand how he could hate annette lmao but he made a character development here. I hope for both of them to be happy, together or not.
