Manga by author Kuze Ran

Kuroiwa Medaka was born in a temple and is currently a monk in training. Because of his temple's rules, he can't interact with girls - and what's more, he doesn't even know how to regularly socialize with them. Mona, the "queen bee" of the school, however insistently tries to make him fall in love with her, but he always ignores her in order to maintain the rules of his temple.
