@Tampon nothing much, just saying that since she was imprisoned since she was 5 and was abused and with such horrible experience, she should not have a concept of m x f relationship yet.
And I think that it should have been implemented better as a character development like learning the meaning of love or something. Just saying that the relationship is developing too fast.
And with regards to the reincarnatin or transmigration, if the FL was one it would've make more sense since she would've have past memories and already know love already.
