I don't really want romance either but how much care towards a child should an adult who isn't responsible for their care and barely knows the family should be? I think it would be kind of creepy if she cared too much or downright wrong if she tried to be mama bear and insert herself. These are the exact things that immediately turn off step children to their new step parents. And as someone who had to be warned what to look for from "creepy uncles" (thank god not my real uncles,) adults who are overly friendly or kind may not have the best intentions.
Over time, she could learn to care more and it would naturally fit. In theory, it will boil down to who MC called to depend on if he becomes too sick to care for his brother. If he can't reach his friend, then he will have to widen his options.
Ofc i completely agree, it's creepy if the girl just take a position as mama bear as soon as they meet. I'm talking in a brother's gf care way, slight interest and compassion is enough really. From what i see she doesn't really show any of that except the moment she met siha and saying that he is cute, and i just don't like her vibe in general in some of the chapter, maybe it is too early to judge since this manhwa only have like 20 chapter, but i prefer to have the purple hair girl to be the fl if this manhwa ever goes to romantic route
I'm fine with a little romance but i really wish the orange hair girl don't become the fl, i rather have the purple hair at the beginning or no romance at all. In my perspective the orange hair girl don't care that much about our cutie pottatooie siha (╯°Д °)╯╧╧
