Absolutely I tried reading the light novel & it got on my nerves .mc is a serious skirt chaser , he runs after every beautiful girl he see plus I am not comfortable with the fact how he sexually looks at his step sister xan xia plus touching her butt & all ...at the same time claiming Mu Ning Xue to be his too ..thanks heaven that she is not much of a pushover & docile like can xia ...Moreover i read nearly 600 chapters but he had no character development ..
