This is Jun Kasui's second release with Honnaka! We went to the fireworks festival with three childhood friends. On our way back, a sudden downpour separated us, leaving me alone with Jun. While we've always been close, lately she's become more feminine and I've started to notice her in a different way. Her skin, glistening white from the rain, her hair clinging to her, and her soaked yukata revealing a hint of her underwear underneath. We ended up taking shelter in an abandoned factory, and impulsively kissed Jun's delicate lips. The atmosphere became awkward, but the rain showed no signs of stopping. "Can you promise not to do anything?" Jun asked me, and... We ended up rushing to a love hotel in the pouring rain after missing the last train.
