I'm hesitant on this one, for all of the reasons people have mentioned, but it also has some very entertaining scenes, when you stop to think about them.
The most blatant is the look of utter revelation she gets when he asks if she's gay followed by her basically going "I only said that to get him to stop, but maybe I—HOLY SHIT I'M GAY!", but there's also the part where Momiji apparently got her sister, who's a professional make up artist, to help with her transformation. So, what, she went "Hey, sis, I need you to make me look like a girl, so I can get with this lesbian I used to bully in kindergarten" and she not only agreed but went all in, to the point of insisting Momiji wear colored contacts. I will laugh if we get a flash back to that scene and the sister basically says "So, you're finally coming out, sis?"
