I mean if it happens it happens
dude they totally will be a romantic pair - that the whole point of the story ╮(￣▽￣)╭
I can see how she can gain feelings for Yus, but not the other way around. She technically met him only recently, but Yus should only be capable of seeing her as a sister.
its literally the other way around yus never thought of her as his sister and her has deliberately showed it in many chapters
I mean I guess XD but *I* cant see them as more, she's treating him as a brother and *I* dont think she should suddenly starts having feelings when calling him as such...(never mind him-)
she acts like how she knows the plot should go, but it clear she does feel things for him and care for him more than just a brother. she pretty much comes from another world so.....but she still ready to trust him, most of the chance more than a brother.
dude I think she had "feelings" for him from the start XD
....I really can't see them as more than brother and sister, I hope they won't be romantically involved
