幼馴染3人で行った花火大会。その帰りに突然の大雨に降られ、1人とはぐれてしまい、なつと二人きりになった。りんは少し子供っぽくて、妹のような仲の良い昔からの幼馴染だったけど、最近急に女の子っぽくなって変に意識し始めていた。雨に濡れてびしょ濡れになった浴衣からうっすら下着が透けて見える。なんだか急に色っぽく見えて、いつもと違うりんの表情にドキドキが止まらない。雨足は強くなる一方で、2人ラブホテルに駆け込む。一線を越えるはずがなかった僕らを、この大雨が狂わせた一夜のできごとー。
Three hood friends went to a fireworks festival. On the way back, we were caught in a sudden downpour, and one of us got separated, leaving Natsu and me alone. Rin was a little ish, a close hood friend like a little sister, but recently she'd suddenly become more feminine, and I'd started to feel strangely self-conscious around her. Her yukata was soaked from the rain, and I could faintly see her underwear through it. She suddenly looked so alluring, and my heart was racing at this unusual expression on her face. The rain only got heavier, so we rushed into a love hotel. This torrential rain drove us crazy in one night—we never intended to cross that line.
