ABO + Detective Conan
As someone who was raised by the Organization from childhood and is a codename member with 100% pure liquor status, Wayne has always hated Gin more than anyone else in the Organization. No contest.
The first time he met Gin as a child, Gin was still a younger version of himself, with cheeks soft enough to pinch. Yet he acted all high and mighty around Wayne, like a complete idiot.
He was obviously good-looking, but he still wore a scowl, as if someone owed him something.
Little Wayne swore then and there that one day, he'd make Gin eat his words.
After being suppressed and forced to work under Gin for so long, Wayne finally got a once-in-a-lifetime opportunity during an outside mission: Gin had been set up, and the mission had gone wrong.
Wayne was swinging a rope and striking a cool pose as he made his dazzling entrance, ready to show off while saving Gin.
Then, as an alpha, Wayne caught the unmistakable scent of a bitter Omega pheromone in the air.
He peered around, then stared in shock at his cold-faced superior, lying half-reclined on the ground, his eyes bulging as if they were about to pop out.
Gin was an Omega!
After discovering Gin's secret identity, Wayne gradually began to thrive in the Organization.
Vodka: Boss, Wayne is way too disrespectful to you. Want me to teach him a lesson? (Cracks knuckles and opens the car door.)
Gin, radiating murderous intent as he covers his face: Get back here!
