Synopsis

Shida Mirai takes on the lead role of Shiokawa Mirai, a 28-year-old woman with no steady job, no savings, and no boyfriend. Still chasing her dream of becoming an actress while juggling part-time work, she’s stuck between ambition and harsh reality.
 
On a stormy night, as she drinks lemon sour alone in her apartment, a boy suddenly appears out of nowhere – calling her his mother! The boy, Shiokawa Souta, claims to have traveled from the year 2036 to reunite Mirai with his father, “Ma-kun.” Thrown into an unbelievable situation, Mirai finds herself living with Souta in a strange yet touching cohabitation.
 
Before long, three completely different “Ma-kun” candidates emerge, kicking off a heartwarming and chaotic quest to uncover the boy’s true father and perhaps, a new future for them both.
