I hope they can be a sister unit. But I also hope author doesn't do the boring "black-haired girl has to be saved" nonsense as usual. It's starting to stink like that far too much and I was already tempted to drop this manga because of it.
The fuck is wrong with your skin color? Are you a disgusting psycheist? Any person with a mental or a psychological disability deserves respect. Stop your hatespeech.
I love how niggacringe that kyapi thing is. Makes me expect to smear turds all over her body any minute and claim it would make a great video if Sera got involved.
Also, I missed the tag before I started reading this. Furthermore, it's simply a theme, it doesn't mean they have to fuck in the end. It can simply be one-sided romantic feelings, as well as one of the main "conflicts" of the story. A non-deranged person would hope the pairing doesn't happen
A non-deranged person knows manga is not the same as real life and that drawings are not real people, so in fiction anything goes and it's fine, a mentally healthy person knows to separate fiction from reality.
