When high schooler Madoka's parents win the lottery, her life takes an unexpected turn. Instead of luxury, her parents decide to chase their dream of becoming doctors, leaving Madoka to live with the Asagi family. Adjusting to her new life in their guesthouse, Madoka finds herself navigating the complexities of youth alongside Tomoyo, the rebellious son of the household, and Ono, a charismatic classmate with secrets of his own. As friendships deepen and emotions intertwine, Madoka must confront the challenges of growing up, family expectations, and the bonds that shape her future.

Sonoda Tamako, a sheltered high school girl raised by her strict, wealthy grandfather, dreams of freedom and life in Tokyo, far from her controlled upbringing. When she meets Tsugawa Norio, a boy from a struggling family, they strike a deal: a fake engagement to convince her grandfather to let her attend university in the city, where they end up living together. As Tamako navigates her newfound independence and her evolving feelings for Norio, this charming tale blends romance, growth, and humor, following a girl stepping out of her sheltered world into a journey of love and self-discovery alongside a boy with his own dreams and burdens.

Shiori, a 16-year-old high school student, loses her memory after a motorcycle accident. Returning home, she struggles to connect with her older brother, Akio, who adores her, and her younger sister, Maho, who openly despises her. At school, vicious rumors label Shiori as promiscuous, isolating her further. Confused by her past actions and unable to recall her former self, Shiori grapples with finding her place. A fleeting memory of Akio saying he hates her deepens her uncertainty about their bond.

Ai Kikuta, a socially withdrawn office worker, is hit by a truck alongside strangers Kenta Makino and Mutsumi Ogata at a crosswalk. The trio awakens in a dreamlike space, confronted by a floating megaphone that offers them an extra 60 years of life if they agree to shake hands daily. Ai, who has always avoided human connection, is thrown into turmoil by the bizarre “game” and her forced bond with Kenta, an outgoing student, and Mutsumi, a reserved woman. Their daily handshakes spark awkward interactions and unexpected emotional growth, particularly for Ai, as they navigate their intertwined fates. The surreal premise unfolds with humor and heartfelt moments, exploring human relationships against a backdrop of mystery.
