Your heart will tell you. Hehehehe...just my POV. It's still in the beginning. I don't know at the future we will see more of her selfishness or not. She looks like girl want everybody attention and affection from such as athy, claude, white hair guy(don't remember how to spell) and maybe others we will see.
Like I had said before, She just care about herself in innocent way author portray her. Also she does not have a commen sense, I think. Look at first when white hair guy together with Athy. When she watching athy with claude. I felt her jealousy but the feeling not portray in strong way. So readers feel she innocent.
I'm doubted she will remain her innocent and we will know her true colour when claude back his affection to athy. Or whoever care for her before, starting turnback from her. I don't know. But looking at her face make me hate her more. I don't like her when she take Athy places even the author just portray her just going the flow and want to keep the secret but in her life she never felt guilty maybe because of she was brainwash tell she is claude's daughter and the reality is not.
Forgive me write this too long.
Imean, shes a nice girl and so. But she gets way too innocent i cant deal with her (in a bad way tbh)
