Katsuki Bakugo is trapped in his mind. Earlier in the year, he was taken by a villain, confined and unable to breathe. Now attempting to overcome his new, unknown fear, he applies for a Fear Simulator program. The program is incredibly difficult to join, considering it is run by only one person. Despite his worry, and pride, he sends an application and manages to get accepted. L/N Y/N accepts a student who is incredibly known for his sour behavior to their Fear Simulator program. Compelled by their own curiosity, they book Katsuki for the two week program, an incredibly rare occurrence. As the two grow closer, they learn, they trust, and they, surprisingly, unexpectedly, love.
