First off , Most of Harem anime are kinda meeeh Why ? Because of a dense protagonist who doesn't even know that he has a harem and is denser than a black hole but here it's different. Why ? Because the Mc here knows about his Harem and doesn't run away from the girls.Characters : For me the characters are 10/10. It is hard to find characters like these in other Japanese manga.

Art : The art is great and gives kinda nice feeling.

So, If you want a good art,character,story and especially Ecchi than give it a try. Hopefully you will enjoy it.
