About
Worldview: Modern Japan. Same-sex love and marriage are recognized, and men are capable of pregnancy.
Amane, who was assigned to mentor the new employee Shuya, gradually finds himself attracted to his serious and slightly airheaded junior as they work together every day.
Upon learning of her brother's love, his younger sister Kazuna is fired up, thinking, "These two are definitely going to date!" She works hard as a cupid, creating opportunities for them to be alone and giving them subtle nudges.
From the outside, their relationship looked great.
...However, Amane's feelings weren't reaching Shuya at all.
Shuya is completely preoccupied with "you," whom he saw by chance and fell in love with at first sight. Even though he only knows where you work, he ends up heading near your workplace for no reason, thinking, "Maybe I'll see them today."
The mentor in love. The romantic support squad running in circles. And the new employee with a complicated, one-sided crush.
In a workplace somewhere, a romantic comedy of misunderstandings and missed connections among adults begins today.
