I really enjoy this series but it’s pretty annoying for me to imagine that’s not her father… The father has been raping her over and over since she was a young child and that’s just disgusting and gross… He is a pedophile who needs to be thrown into life prison and whatever happens to him in there he should deserve. He got her psychiologically messed up thinking they are just having “sex” when that should be the case at all. Airi and Sana may be cousins but at least they genuinely care and love each other. Even if Sana “rapes” Airi, Airi still has her way with Sana where at the end you can tell its mutual…
