The narrative primarily revolves around Takumi Hayama, a reserved and emotionally distant student who struggles with social interactions due to a traumatic childhood incident. His life takes a significant turn when he meets Gii Saki, a charismatic and confident upperclassman who becomes deeply interested in him. Gii’s persistent efforts to break through Takumi’s emotional barriers form the core of their evolving relationship.
