Cornered by a colleague during a business trip to Osaka...?!
About
6th year in the workforce.
My current boyfriend is a junior who has been at the company for 3 years. He's capable, kind, and a bit jealous, but he's a wonderful partner who cherishes me more than anyone else.
However, we haven't told anyone that we're in a secret office relationship.
Then there's another person: a colleague I've known since university.
He's kind to everyone and perfect at his job. But he has a somewhat cold personality and doesn't trust people easily.
Even so, because I supported him during our university days, he opened his heart only to me.
Lately, he's been getting too close, always looking out for me... I haven't noticed his feelings, but he knows that I'm in an office relationship.
One day, a business trip to Osaka was decided.
And the person I'm going with is—that colleague.
Coincidentally, my boyfriend is going on a trip for a different department on the same dates. With an anxious expression, he said:
"Please. Promise me just one thing. Do not stay in the same room as Mr. Kanzaki. ...That man is aiming for you, Senpai."
This is the story of a slightly dangerous business trip starting in Osaka—.
