Scumbag, Change Your Identity at Any Time

I heard that people will read it only if the introduction is awesome, but I also think it makes a lot of sense. What's the point of bragging so much at the beginning? The protagonist is outrageous? There are still three thousand beauties in the harem? If I can't stand it, I'll change my identity. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
