Natsu ni Tokeru Himitsu no Koi

Natsugami recalls a boy named Aki whom he met in an abandoned building, a memory complicated by the trauma of witnessing Aki being harmed there. When his junior, Miyoshi, confesses feelings for him, Natsugami is unable to engage emotionally due to his unresolved past. To confront both Miyoshi’s confession and the lingering mystery of Aki, he returns to the abandoned location, with Miyoshi following closely behind.
