From Kodansha:
Five girls who want to do anything but study, and their tutor: a high school boy who's got book smarts and not much else. Futaro Uesugi took the tutoring gig because he was desperate for cash, but when his students—the five beautiful daughters of a wealthy businessman—find five times the excuses to slack off, what can he do?! At this rate, the sisters won't graduate, so if he wants to get paid, Futaro must think of a plan to suit each of them … Which feels hopeless when five out of five of them think he's a lose

Official English: INKR, Azuki

Note: Won the 43rd Kodansha Manga Award in the Shounen Manga category in 2019.
