Dude, this is actually pretty good.
It has some psychosexual Freudian shit in a good chunk of it (paraphrasing: you look like my sister therefore I wanna bang you) hahaha, and is very faithful in its theme: lying. The various lies we tell and the effect they have, and how the become a snowball. And I think is pretty funny, the art got really good as it progresses and I also could understand the characters motivations well.
Is very shoujoish I guess, and most conflicts get resolved with ease and without much consequence, which is a bit of a bummer, but makes for a light-hearted read.
