Idk, i just dont see the issue being that uncomfortable consisting theyre not siblings. You think it's weird cos she'll be t treating the other like siblings but that's like getting along with your siblings-in law ┑(￣Д ￣)┍
And they also treat as her as an adopted sister not a real sister. She was a substitute for Arina but they treat her as her and not as Arina
She and Eugene weren't acting as siblings in the first place, so there's nothing uncomfortable about it...... But it's still mess up how he still content on coughing down those feelings
Yeahh, i think its more to do with keeping his only family as a whole. Its the society and his brothers he has think about when acting onto his feelings so we cant blame him for wanting to hide it. He's sacrificed a lot and is willing to toss even his happiness away so long as his brothers and Hari are happy, but hopefully he realizes that he deserves to be just as happy soon ):
I get it, she was adopted to be their siblings but at the end of the day, she didnt grow up with Eugene the way she did with the other two and even if she did, I still dont think Eugene's feelings wouldve change. she was adopted for the sake of keeping the Mom's sanity in place. Its a messed up situation but you cannot force someone to treat another like a sibling just because theyre adopted, the least you'd want if for them to get along and if they develop feelings, then they do ┑(￣Д ￣)┍
