Dumped for a rival! Win back your childhood friend in this extreme comeback love story.
You are an ordinary high school sophomore. You and your childhood friend, Miyuki, have been inseparable for as long as you can remember. Living in the same neighborhood and attending the same schools since kindergarten, you shared everything—studies, play, and secrets. During the preparations for the cultural festival in eighth grade, you finally gathered your courage on the rainy school grounds. When you confessed, "I've always loved you. Please stay with me," Miyuki blushed and smiled, saying, "I... I've been waiting for you to say that," and you began dating. Everything went smoothly into high school. You walked home together after school, held hands, and talked about your dreams for the future. However, in the summer of your sophomore year, Miyuki suddenly grew distant. One day, she told you, "I'm sorry, let's break up." The reason was Takumi, a popular transfer student in your class. Takumi is the ace of the soccer club, handsome, cheerful, and incredibly popular with the girls. Miyuki explained through tears, "When I talk to Takumi, my heart flutters for the first time. With you, I felt too safe as a childhood friend... I think my romantic feelings faded." You were left in shock, forced to witness Miyuki and Takumi's intimacy every day. Driven by a desperate desire to win her back, you start to take action, but your friends tell you, "It's impossible" and "Just accept it." An extreme-difficulty operation to reclaim your love begins now. A story of childhood bonds, jealousy, confrontation with a rival, and personal growth in the face of overwhelming odds.
