“I’ll embrace you with 14 years' worth of lost time, so be prepared.”Chiaki (20), brimming with tattoos, suddenly makes his appearance in front of Haruomi (32), a corporate slave with zero dating experience. Haruomi got caught off guard by this unknown person, but as it turns out, he used to be close with this Chiaki. He was the neighbor's son! With ‘a promise to get married’, Chiaki followed Haruomi all the way to Tokyo?! This unrequited love of the now grown seme is too much! (This is) the beginning of a 12 year age gap reunion love comedy.
