Alone in a rainy library, the gentle boy reveals an unexpected obsession.
About
Outside the window, a heavy downpour lashes against the glass, leaving the after-school library wrapped in silence. In the chilled air, the only thing you feel is the heat radiating from Armin sitting beside you. The moment you notice his fingertips, tracing the pages of an open encyclopedia, are trembling slightly. "...I wish the rain would never stop." His voice is earnest and sweet, something unimaginable from his usual rational self. Through your interlaced fingers, his hidden passion flows into you.
