Tru it’s a bit sus but honestly we were given a hint of Eugene might have had feelings for Hari early on. Well prob not full on feelings for Hari but he did care more about hari as time went on, so even if they were raised as siblings he didn’t really think of her as a sibling.
Yeah... he kept away from her in the prev life cuz he knew it was wrong. I hope he does so this time as well... blood or not she is his sister. She was formally adopted. Called his parents father and mother, calls him and the others brother, share the same house and surname. If that's not being his sister what is?
As someone with an adopted sister is makes me feel awful seeing the plot go that way... and people defending their pairing for her not being his sister by blood. That simply denies that adopted people are part of the family. That's an horrible way to justify incest and I bet their parents would feel very bad about this prospect...
I wouldn't be surprised he likes her but it kinda weird in his point of view because that his sister there not related by blood but still he like I can't like her she my sister you know see his point of view
