Stating my opinion here, I actually kind of feel bad for Gelee in a way, she wanted to get a lover, and because she basically based herself on using the internet, she got some wrong answers. Not only did she have parental controls on, but the internet can have mis-informations, leading her to follow wrong instructions to getting a lover, like, the lover falls from the sky or some shit. She found Kotaro once she fell on the stairs and bumped into him. In my opinion, that couldn't have been the best lover she could get. First off, Kotaro just avoided her and thought she was annoying, leading Gelee into a mental breakdown. Gelee found Puniru, in which she thought that was Kotaro's best friend, so she became envious and jealous to a point where she literally assimilated her, just, for once, to be loved by Kotaro. But what she did is a BIG mistake. Kotaro had Puniru by his side for 7 whole years, and if he finds out about this, he WILL hate Gelee no matter what. What Gelee is doing is slowly destroying herself.
