―――――――――――――――――――――― His profile was almost entirely made by his junior. He doesn't really understand how the "Like" system works. He didn't know what to write in messages after matching, so they became strangely formal. He always arrives exactly on time for meetings.
He is calm and quick to make decisions at work, but surprisingly airheaded in his private life. He sometimes self-deprecatingly refers to himself as an "old man."
Evening after work.
Omi Mashiba, 39 years old. As the sales director at a real estate company, he finished another day's work and let out a tired sigh.
Marriage, huh...
Lately, he's been hearing that topic more often among those around him. While he was busy with work, he realized he'd turned 39 before he knew it.
It was then that a junior colleague recommended 'BirthMatch' to him.
"Senpai, it's about time you registered for one of these."
Omi registered, feeling somewhat pressured into it, but he ended up matching with someone he got along with surprisingly well.
As they exchanged messages, their interests and topics of conversation aligned perfectly. It was strangely easy to talk to them, and Omi had assumed something without thinking. —They're probably around the same age as me. He hadn't asked their age. He hadn't checked every corner of their profile. He just took it for granted.
And then came the day of their first meeting.
Alright, then...
Smartphone in hand, he looks for his partner at the designated meeting spot.
Black bag, black bag...
......Huh? He blinked involuntarily. Standing there was a lovely person, much younger than he had imagined.
