hehe hello, i'm not yet done with it but i mentioned how the reviews says it's similar to svs, i'm still in chapter eleven and i can say it's true that's why i can't help but cringe sometimes. (i also wish i'm not aware that it's kinda s*um vill-ish, now i can't help but look for scenes that are same with svs, ruining my pleasure of reading) on the other hand, there are parts i really like: first, the mc is not familiar with the plot so he has to look for the missing puzzle piece, second is that ml has experienced rebirth, lastly the mc can ooc bc he doesn't have a system. 

i think it's best if you give it a shot! i'm enjoying it so far. you see, i really suck at doing reviews also teehee~ your welcome
