Please Take Care of Our Asano

The manga centers on Mami, a normal high school girl, and his not-so-normal relationship with Asano. Asano, the actor (though not popular). Asano, the genius (though he gets too serious in his roles and loses his job). Asano, the hottie (though nobody knows about him). Asano works at the neighborhood convenience store near Mami's place, which provides her an opportunity to be with her beloved. But in the throes of her passion, she is suddenly roped into becoming the store's manager.
