This project presents attractive male characters in a dating sim format, but questions the usual focus on romance. It explores the idea of how characters would feel if players keep interacting with and bothering them. Instead of building relationships, the project focuses on characters who still have their primal beast instincts, and how they react when pushed too far.

There are three main characters: Leviathan, Siren, and Nian. Each is based on a mythological beast and reimagined in a human society with different personalities. Leviathan is an unstable scientist, Siren is a famous idol with a beautiful voice and strong personal boundaries, and Nian is a playful Chinese mafia figure who cares mostly about his own fun.

The interaction system reflects each character’s personality through different reactions. All characters share one core feature: when their irritation meter is full, a special animation is triggered, revealing their true beast form.
