Unfortunately, Satoru Muka hasn't been in a romantic relationship for 10 years. He suddenly realizes that, around him, he is the only single person. His friend has recently become a father and his younger sister has gotten married. Satoru Mukai wants to have a romantic relationship and looks to find the right person for him. He believes it won't be easy for him, because he knows women who are friends with him, but they aren't available for romantic relationships. He asks himself the reason for that and begins to find errors when he makes romantic relationships.—AsianWiki
