From Renta!

Kuze is a first-year student at a boarding school attended by the sons of wealthy Japanese families. One day, the serious and good-natured athlete is suddenly nominated to become a Prefect. The nominator is Hanabishi, Royston Academy's biggest playboy. He is one of the richest, smartest, and most talented Prefects in the academy. Why did the student representative's right-hand man nominate him of all people...!? Kuze wasn't a fan of Hanabishi's, but the more he gets to see and know Hanabishi, the more attracted he becomes.

The start of a dramatic love story where the underclassman takes the lead at a school with its own rules and hierarchy!!
