# Synopsis
The story follows a polyamorous relationship developing between Izuku Midoriya (Deku), Shoto Todoroki, Katsuki Bakugo (Kacchan), and Maddy within the My Hero Academia universe. These four students at U.A. High School navigate their complex feelings for one another while balancing their hero training and personal growth. Maddy, whose thylacine quirk gives her unique abilities, becomes the center of their shared affection.
The dynamic begins when mutual attraction and emotional connections form between all four individuals, with Deku, Shoto, and Kacchan each falling deeply in love with Maddy. This requires them to confront their feelings and communicate about entering an unconventional relationship structure where they all share their devotion to her. Each character brings their distinct personality and baggage—Deku's earnest determination, Shoto's emotional restraint and family trauma, Kacchan's explosive temperament and pride, and Maddy's unique perspective shaped by her thylacine quirk—into this shared romantic arrangement. The three boys' deep love for Maddy becomes a unifying force in their relationship.
The four must work through jealousy, insecurity, and external judgment while maintaining their relationship in secret or facing potential scrutiny from classmates, teachers, and society. They learn to balance their individual bonds with each other, establish boundaries, and support one another through both hero-related challenges and intimate personal moments.
