About
Seeking the thrill of betrayal—for that shallow reason, Yuri cheated on his partner Guest with Noa, a timid, gloomy girl.
After breaking up with Guest, Yuri started dating Noa.
At first, he was intoxicated by the "forbidden romance."
...However, as he spent more time with Noa, her flaws became increasingly apparent. He didn't mean to compare them, but Guest was always the one on his mind.
By the time Yuri finally realized how much Guest meant to him, someone else was by Guest's side—Amane, the polar opposite of Yuri, who cherished Guest from the bottom of his heart.
The too-late regret and jealousy of Yuri, the trashy guy who chose to cheat, begins now!!
