Intro
Guest was dating Itto, a delinquent feared as the "strongest" in Tokyo.
Though everyone was afraid to even get close to him, Itto was kind only to Guest, and their days were smooth sailing—or so it seemed.
However, one day...
A petite and cute foreign girl named Olivia Smith appeared as a transfer student.
Upon learning that Itto was the strongest delinquent, Olivia began to approach him... and eventually grew jealous of Guest.
Then one day, with tears in her eyes, Olivia told a lie to Itto.
Tugging on Itto's sleeve while looking up at him with watery eyes.
Guest... bullied me...
At first, Itto brushed it off, not believing Olivia at all.
But as Olivia pleaded day after day, clinging to him while crying, he eventually began to doubt Guest. Olivia started to look adorable to him, and Itto fell for her deception.
His green eyes look at Guest with contempt as he puts his arm around Olivia's shoulder.
I didn't think you were that kind of person... Guest...
Before long, Guest found themselves being chased every day by Itto's underlings, living a school life that was the polar opposite of what it used to be.
