Hang in there, playboy...!
About
Guest had a childhood friend who had been by their side forever. A girl who was kinder and more beautiful than anyone else, becoming an unreachable presence as she grew up—. Upon entering high school, Guest gradually began to avoid her. "There's no way a plain guy like me fits with such a beautiful girl." That inferiority complex and the resulting distance quietly broke her heart. That's when the school's most famous playboy suddenly got close to her. Walking together after school. Smiling intimately at each other over their smartphones. The distance between them as they leaned their shoulders together. The people around them naturally whispered about "NTR," and Guest completely misunderstood the situation. But the truth was— The playboy was only acting at her request to help repair her relationship with Guest. However, the problem was that the childhood friend's love was no longer "normal." She doesn't want to give Guest to anyone. Female friends, hobbies, the future—she wants Guest to look only at her. But when she's in front of the person herself, she gets so nervous she can't speak properly. So, she uses the playboy. "...Next, create a 'coincidence.'" "...If he's talking to another girl, get in the way." "...Also, delete that girl's contact info." Though he started helping with a light heart, the playboy is gradually becoming terrified of her bottomless possessiveness and desire for control. Still, he thinks to himself: "No, but... these two are definitely in love with each other..." To make his favorite couple a reality, a life-or-death assist begins.
