Please PLEASE tell me she does not get with Dietrich
Better crush your hope now rather than later.
So... yes, she will. He is not her brother by blood. And he don’t think of her as his sister. He likes her in romantic way very quick. Like... after spending 1-2 years with her, he start liking her in romantic way.
While, she treat him as a kid that still need to eat a lot and drink milk to grow up.
I think their age difference is between 6-8 years apart.
Very soon, she will meet 2nd male lead who is about same age as Dietrich. He is cutie Tsundere. And in my opinion, Dietrich is a mix of Kuudere + Yandere.
The semes still a dick but I think is probably the first time he’s ever said sorry
