I don’t understand why people are so conflicted about Eugene and Hari’s relationship... people seem to think of them more as siblings than they themselves do. They aren’t related, the only reason she became their sister is because she has similar characteristics to their dead sister. Also even if she looks alike to her when she’s young, she’ll grow up to look different. Hari always felt like an outsider within the family, she cared for them but never truly felt like a part of the family until later in life where she still felt different. Feelings of love is vague in itself, you could not realize you truly love someone unless something happens. The timing of events create a moment for them to realize their true feelings. The readers who are assuming they see each other as siblings and that this whole plot is just incest need to realize that Hari cares for them all but felt special towards Eugene even in the past. She wanted to protect him and be there for him, and that can sprout into love. For Eugene and the family, Hari is just a random girl they meet one day to replace their dead sister until they have to see past that. Once they do, they’ll care for her, but it doesn’t necessarily mean they’ll immediately see her as their sister. They could still see her as childhood friend or even just a friend or a girl. Think about it, if a random person comes up to you announcing that they are now your adopted sister, can you immediately care for her as much as you would any of your other family members? Would you immediately see her as your life long sister and not as a someone you just met or are getting to know?
