The writhing suck i see no reason why like the reason also almost no backstory whatsoever, all girls falling for mc for no reason, getting power of top 3. job from combining 2 0. job powers makes no sence, transformations from nowhere and nonsencual power ups and power scale why tf does non of the quesnt have any failiure penalty? its ok for some filler manhwa for recoery from peak but as a series it sucks
