Review Detail of Yardigan in I'm Kizaru in Konoha

So far this is a 5 star novel, but before I get further infested into this, I would like to know if this has romance, if yes, is it a single love interest or is the character going to be picking up multiple girls for no logical reason. It's not that I'm against harem novels, I'm just tired of seeing every single novel about an mc with 2 or more girls.
