Nope, I am too. To me they make absolute sense. I'm just too lazy this time to look up the chapters so I can quote all of them them. Though I can share this one gem from chap. 31 which is one of my fav: "My feet freeze up in front of Rowoon... Even though I managed to handle it well with Jaeon and Seo Jungwon, why do I only get like this on front of Rowoon...?" Then in chap. 32: "At first, I was a bit scared of Rowoon (...) but then I realized he's living his life in his own way (...) and I found him kind of cute. Wait, no, that's not it! Why do I keep having thoughts like this...?!" Our mc knew she liked him since a long time ago, it's just readers forgot because the story then went to focus almost completely on Miss Crazy Purple-Head.
Exactly, for me it was them from the get-go, he is the one who sees her for her (not the sister) and accepts her for that. He questions himself, tries to be better. Maybe he is not crawling himself to her but I think it's better for both of them, because they can be on the same level, hold each other accountable for their actions and become better as a couple. And yeah, he is the one she has feelings for and there is also a sense of understanding, because he is not above her (in position), he is not trying to save her but to support her and also the two of them grew up in that twisted place. So there are things only them can understand...
Feels like I'm the only one rooting for Ro-eun haha...
