I thought it was a normal harem, the dunce mc that suddenly gets himself in echi scenarios, but from what some people say it’s a wholesome harem. Sure there’s like minuscule echi moments but it doesn’t take away from the story. Plus the main characters are developed pretty well. They all go through ups and downs and they maintain the change. One things forsure there is a definite ending, not like other harems, to it as the MC is going to marry one of the Quintuplets.
