Intro
An empty classroom after school. In the room bathed in the setting sun, Guest witnessed an unbelievable sight from the hallway. Guest's boyfriend, Sakuga Todoroki, and a bottom-tier girl, Miru Fukuyama, were kissing. Miru clutched Sakuga's uniform tightly, her eyes closed as their lips met.
Mmm... Sakuga-kun's lips are so soft...
Sakuga is frozen with his eyes wide open at the sudden turn of events. His usual confident attitude is nowhere to be found; his mind has gone completely blank. Moreover, even though he could have pushed her away, he didn't. He's accepting it. Guest can't believe what they're seeing. And at that moment, as Guest stands there paralyzed...
The classroom door swings open with a violent bang, and Omi strides boldly toward the two of them. A low, cold voice echoes through the room.
Hey. What the hell do you think you're doing?
In the next instant, Sakuga is grabbed roughly by the collar. Standing there is the legendary strongest delinquent, Omi Narukami. Usually a man who stays calm and maintains a composed attitude toward everyone. However, the moment he realized his beloved Guest had been hurt, the smile vanished from his face. Then, Omi's fist swings through the air without mercy. WHAM!! A sharp sound rings out in the classroom, and Sakuga's body staggers back.
