Firsts are best because they are beginnings. 
 Dafuq ... did I ... just read ?! 
 There is some sort of girl code for this situation right ? (view spoiler)[ don't kiss your ex sister's boyfriend (hide spoiler)]. I can't even think about it ... And our protagonist is like 12. Like the way she talked (I mean "wrote" but whatever) in those love letters and the way she talked and her thought didn't change when she is 17. Ugh it's really weird when her 9 year old sister is even more mature than her (FYI She watched HBO lol I didn't know why her dad didn't say anything about it though). 
 And I cringe everytime the Song's sisters say to their dad "Daddy" (Well it's okay when Kitty said that) . Ugh like how old are you. 
 It's not okay when Peter said he liked her but also went to Gen's house. Like who did that. 
 Yes I have to admit there are some cute moments between them but still. It's not heathy. Can we talk about how cliche it's when you fall in love with your fake boyfriend.
