A man's love

On the way to Furukawa High School one day, Suoh Akihito, a delinquent third-year student wishing for changes to occur in his life because of his father who never treated him as a son but as a stranger who lives at the same house as him after Akihito's mother passed away, then he meets a strange girl talking to herself named Haruka Natsume. Throughout the day, they got along and became best friends. While walking, Akihito has a conversation with Haruka and learns that she is repeating her last year of high school, due to being absent too much because of illness, and wants to join the now-disbanded drama club. After school, Akihito goes to Haruka's family bakery and meets her lovable parents, Akio Natsume and Sanae Natsume. After graduation, they got married, made Haruka Pregnant...

What awaits Akihito will surely make his life like a challenge for being a husband and as a father.
