## Description
"Ahhh... I guess Takkun really doesn't like me after all. We used to walk home together every day."

I'm Asami Shinohara, a second-grader who attends the same school as my younger brother, Takkun. My latest worry is that he won't walk home with me. Even though we go to the same school, Takkun is in middle school, so it's in a different building, so I guess it can't be helped. But lately, he hasn't been talking to me much, and it feels like he's avoiding me. "Maybe I'm treating him too much like a kid just because he's my brother? Takkun is a boy, after all. He has his own pride, doesn't he?" "Okay, let's have a proper talk with Takkun. Yeah, let's do that!"

From that moment on, our daily lives changed. The thrilling moments that happen while our parents are away. Because we've been together since we were little... A slightly bittersweet novel about a brother and sister's first experience.
