You watch this for the same reason you keep a specific friend's number saved: some people just make existing feel like enough. Five childhood friends moving through a school year together sounds simple until you realize the show has no interest in manufactured drama, just the actual weight of growing up alongside people who already know you. By the end, you'll understand why they promised to keep laughing together, and it won't feel sentimental, it'll feel inevitable.

Twins Yuta and Yuki, along with Kaname and Shun, have been friends since kindergarten, and transfer student Chizuru has made their group of five even livelier. In this second season they reach their third year of high school, and daily life keeps bringing mishaps both at school and in love. Through the passing seasons the boys meet laughter, surprises, romance and new people, growing a little every day in a gentle comedy and slice of life drama.
