Hatsukoi Losstime

Aiba Kouji, a student uninvolved with girls, experiences a strange phenomenon called "loss time," where time halts for one hour each day. During this frozen period, only Kouji and Shinomiya Tokine, a girl with red eyes capable of moving within the stopped time, remain active. As the two interact in this isolated world, Kouji's feelings toward Tokine begin to shift into first love. However, Tokine appears to be hiding a significant secret that affects her emotions. The story is adapted into a live-action film.
