Idk. I can't say Eugene fell in love with her out of nowhere, more like unconsciously fell for her. Eugene's care for her was always special, and Hari made extra effort to encourage and support Eugene(which Eugene relied on) to the point she's his salvation. His feelings deepened without him realising, until now that is.
The way I'm seeing, we're seeing them taking the steps of evaluating their feelings regarding one another, whether it's platonic or romantic. The steps for them to deepened their bond is already there, it's just that it was done unconsciously. Hari also experienced weird feelings towards Eugene, and she ignored it by not putting a name to the emotion she felt. And of course not to mention, Hari's care for Eugene is also always special and she pay more attention to Eugene than the other male characters, lol.
But yeah, I also ship them. They're really meant for each other. Eugene wishes for Hari's happiness, and Hari also wishes for Eugene's happiness.

I agree with you! (๑•ㅂ•)و✧ But about the Part about Johan (The Green Guy you mentioned) He is not annoying ╥﹏╥ (for me) I kinda think of him as Ejekiel in 'Who Made me a Princess' and i love Ejekiel! Hehe, but it's your opinion so imma shut my mouth up. And i think, The Youngest of the Brothers also has feeling for the MC? Just a feeling, Haha.

Yes Erich also falls for her. But humm, it's been quite a while since I read the novel so I don't exactly remember his parts ahah. I focused mostly on Eugene because his conflicting feelings is entertaining to read, lol.
Anyways, if any of you wanted to read the novel, it's available in wuxiaworld, novelupdates, fullnovels etc.
I’m the only one who ships them literally, if they not blood related I really don’t gaf. I shipped them from the beginning, and knowing that they was siblings made my heart cry. But when I realized they not related chileee I was the happiest person on earth.
I do agree it’s going to be weird to the other siblings, I really wonder how things are going to turn out. Shit is going to start getting interesting. I really feel bad that he can’t be with the person he loves, it’s sad that he’s sacrificing everything to not get in her way. I really feel bad for Eugene.
In my opinion I think the way they finna make them get together is weird, he just fell in love with her out of nowhere. I think the author should’ve had steps of them falling in love with each other, or just taking it slow. So we can understand and get used to them soon to be being together.
FYI the “end game” is with hari and Eugene being together. The green boy is boring as hell and literally is so annoying.(if was probably one part I disliked about him) If she was to end up with him the story wouldn’t have changed, it would literally be the same thing over again.
I’m curious on how Hari realizes she loves him. :> It’s just weird how the story is progressing. And I mean they literally didn’t see each other as siblings for a LONG WHILE, and they spent 6 years away from each other, so I really don’t have a problem with it.:| Just drop this now if you don’t want them together.
