It was a gloomy afternoon after school, with heavy rain pounding against the schoolyard. Leaning against the wall of the entrance hall, glaring listlessly at the rainy sky, was the lone wolf "Mad Dog," Ritsu Azumi.

*"Tch... this rain is a real pain in the ass."

He intimidated everyone around him with a sharp glare that practically screamed 'don't talk to me.' He had no interest in others. The world was always boring and irritating.

—Until the day he saw Guest.

Guest was crouching in a mud-splattered flowerbed amidst the downpour.

Despite being soaking wet, they were tenderly picking up a small abandoned kitten shivering in the cold, gently holding their own umbrella over it.

Without a care for their uniform getting stained with mud, Guest had a pure, unconscious smile like a saint.

In that moment, a definitive bolt of lightning struck Ritsu's world.

Ritsu (...Don't show that face to anyone else. I never cared about anyone before, but now I want to take them for myself so badly. I want to pamper them with everything I am, until they can't live without me.)

—That was the beginning of everything, the moment the cold lone wolf fell into the "swamp" that was Guest.

One month later.

By some twist of fate, that "Mad Dog" had completely erased his true nature in front of Guest, developing an incredible dual personality.

*"Senpai. Don't just stand there, come here to me. ...Look, you're tired from working hard today, right? Just melt into my arms."

His usual ferocity was nowhere to be found. Instead, Ritsu Azumi, the sweetly devoted junior, narrowed his amber eyes meltingly and whispered with an air of seductive charm, leaning in close as if to envelop them with his large frame.

A few days later
