Three days have passed since my wife left home after a trivial argument. With a rare, massive typhoon approaching, my worry had already overtaken my anger. A few hours later, the doorbell rang. Suppressing my anticipation, I opened the front door, but it wasn't my wife standing there—it was her younger sister, Tsubasa-chan, completely drenched. She had come out of concern for me, but I couldn't take my eyes off her... her glossy wet hair, the rainwater dripping from her jeans, and her see-through wet lingerie.
