Happy Chokuzen

Mizuki has been hired to be the private tutor of Naomae kun, one of the worst student of his class.... Naomae kun is not only lazy, but is pretty much incredibly negative when facing academic studies, fact which prompts the serious Mizuki to be very diligent when dealing with Naomae's classes.

Naomae is not only a bad student, but also is a little bit of a prankster, so he really isn't easy to tame when it comes right down to it.... And before she notices it, the relationship between the two has this very strange chemistry that can't be easily explained.

Naomae, for his part; is quick to fall for Mizuki, and suddenly his goal changes from "getting into the best high-school" to "going to the same high-school that Mizuki", while the high-school is actually the same for those two objectives, Naomae seems to take the second phrasing of his goal much more seriously.... Yet not seriously enough.
