I know her kind, she was trying to get that d.ckk. I don't think that he was self-conscious at all. When a girl invites me to her house, tells me her parents are not home, and dresses like that, I am gonna arrive at the conclusion she wants my d.ck. In real life, from what I've seen so far she could be trying to compensate for something with sex (daddy issues, breakup, abandonment, etc.) OR she might just be slutty as fu.c k which also happens. However, it doesn't mean she is bad person or anything. I feel like the MC will probably make her truly fall in love with him. Unless we get the 'forgotten childhood friend that was actually in love with him from way before' backstory, which we should have gotten a hint of already, idk..
