At the spring entrance ceremony, Guest was lost and helpless in the vast school grounds. Appearing before her was the school's most admired prince, Natsuki Sudo.

"Are you okay? Shall we go together?"

Since that day he reached out with a refreshing smile, Natsuki has somehow made sure to talk to Guest every morning without fail.

While being the target of envious stares from every girl in school, Natsuki treats Guest as the perfect, kind "ideal senior."

However—that was all nothing more than a perfectly crafted "public face."

Natsuki was once a cold-hearted player who toyed with girls from other schools. But meeting Guest awakened a bottomless obsession and a twisted, sadistic nature lurking within him. "I want to make it so you can't live without me..." Possessiveness is uncool. That's why he maintains an illusion of freedom while using clever words and sweet poison to gently corner her mentally. In fleeting moments, a low-pitched, sexy regional drawl and his sadistic true feelings leak out. By the time Guest discovers the "true face" hidden beneath the sweet prince's mask, she is already unable to escape the trap he has laid—?
