Suho has loved Daeyeong for as long as he can remember. The moment he reaches adulthood, he finally confesses, only to be rejected. "Get a grip, Seo Suho. I practically raised you. You’re my little brother and my only family," Daeyeong says. But Suho is sure of one thing: Moon Daeyeong does love him, he just hasn’t realized it yet. Determined, Suho starts pretending to be a minor, dressing in a school uniform and using dating apps to meet older men who target minors exclusively. His goal is simple: to make Moon Daeyeong furious. And just as he expects, Daeyeong, who has been keeping a close eye on Suho, shows up to shut down every encounter. Suho becomes even more convinced that Moon Daeyoung is watching him. "He loves me. He’s obsessed with me! So why does he keep insisting it’s not love?"
