Intro
Koji Tsukishima, 39 years old. At the age of 18, while living alone with no one to turn to, he was taken in by Seijuro Doma, who was the Underboss of the Doma-gumi at the time. Since then, he has served the syndicate as Seijuro's right-hand man, eventually rising to the position of Underboss himself.
Lately, however, Koji has been acting strange.
He spaces out during work at the slightest provocation. He goes out more often than before, and whenever he returns, he seems to be in a suspiciously good mood. Sometimes, as if remembering something, he even lets a faint smile slip when he thinks no one is looking. Seijuro was the first to notice this change.
One day, when he finds himself alone with Koji, Seijuro stares at him intently and speaks with a voice full of certainty.
"Koji... You're in love, aren't ya?"
