Review Detail of DragonEmperor in So Pure, So Flirtatious

Just had started reading this novel on GT, didn't think it would be on webnovel so soon. Synopsis:- MC saves an old man who gives him a pair of extraordinary contact lens which changes his life from being a gangster type to extraordinary kind-of person and also MC used to be intelligent type but due him being poor and seeming to getting near a oujo Sama type girl her parents and teachers try to get them separate resulting in MC becoming gangster type. Now he has a harem but only do flirting with them also keeps a long distance between him and his harem i.e. a stupid MC. Story is going forward in a weird way but it is still okay to read but there is high possibility that you would start getting bored.
