A really nice review of this series.

for those who dont want to watch the video, the manga is shit and leave out alot of things that make this series more enjoyable, go read the LN, dont know bout the anime
And for those who has a issue with him a pervert, yes i wont defend him bcs he is but just imagine cooping up in a room most of his life, hes bound to have a fucked up thing in his head. I am not trying to justify him, its just I want you to understand. He's basically the lowest of society but you gotta respect his honest desire to change. Again, please read the LN.
