after 250 chapters, the MC suffers the same as Road the Kingdom. Instead of progress its a regress, mc steadily becomes more and more retarded. He is the strongest wizard but day to day interactions really take a nose dive, along with quality of writing around chapter 40. There is almost no relationship progress for a supposed harem, like none (even fucking To Love Ru has some progress). Around chapter 200 I thought there would be some progress with one of his party members as the writer went with the fake marriage troupe but nope. It went through the paces then that was it. Just a kiss to attempt to convince mommy and daddy then nothing. Millet and ViVi get no development what so ever. After the hero party is introduced Millet becomes a side character. She tries to lay it all out there but gets noise blocked and then it never comes back up.
