Her Gentleman's Code

A gentle female lead who grows over time, an invisible heartthrob. Who could resist a partner who knows how to take the lead? (An incognito heartbreaker: she never makes the first move, but never turns anyone down.)

An unconventional setup. The main characters are mostly obsessive oddballs: a brutal, bloodthirsty Demon King, a gentle and fragile senior student, a cool and chaste saint, a sunny, warm-hearted mermaid prince, a composed and rational AI android... (Their genders aren't set in stone.)

No matter how powerful or beautiful they appear, remember that they are all extremely dangerous destroyers.

The world is on the brink of collapse. Love is the only rule.
