Nakahara Yusuke is a high school boy who has a very loving younger
sister, Maria. She loves spending each day taking care of him, doing
things such as cooking and cleaning around the house. However, she
typically goes a bit too far into treating him like a child--she has a
habit of coming to his classroom at lunch to hand-feed him his bento, or
brushing his teeth for him at home. She even snoops out his hidden porn
magazines. Other people think they're a bit weird, and that Maria acts
like his lover or his mom. This 4-koma features their unusual daily
life!
