pretty sure they’re siblings, maybe just trying to make him jealous?
I was thinking that should be the case. But her boyfriend seems somewhat suspicious of him too. And why would he react that way towards her own brother? It's just weird lol.
the sister never mentioned that our mc was her brother. just called him her oppa, so boyfriend probably misunderstood? idk how this is shounen ai so far.
Someone mentioned that in the beginning it stated how they both visited their mom? I would have to go back and read that myself. And I've seen the raws, so while it's confusing I can see that something develops between them.
i’m looking forward to that then!
Not gonna lie I genuinely thought they were siblings. They really don't come off as friends and she relies on him a lot. But I guess that door code comment was for a reason. Now unless I missed something that already revealed this, but that was interesting. More confused why she would try and make her boyfriend jealous with that comment.
