It's been nearly a year since I started living with my older brother and his wife at our family home. All this time, I've secretly harbored feelings for my sister-in-law, Rena. She was supposed to return today from an overseas trip, but due to a sudden typhoon, her return was delayed. Alone in the house, lost in these forbidden thoughts, the doorbell suddenly rang. Rushing to the entrance, I found Rena standing there, drenched by the rain. My heart pounded at the sight of her—her glossy wet hair, rain dripping from her jeans, and her soaked underwear clearly visible through her clothes. I couldn't tear my eyes away. All the desire I'd buried deep inside surged forward, impossible to control any longer.
