After my parents' remarriage, I found myself sexually attracted to my stepsister, Roa. One day, I accidentally caught a glimpse of her pubic hair peeking out from her underwear, and from that moment, my curiosity became uncontrollable. Initially tormented by guilt, I continued to secretly watch her while she slept, but one night, she caught me. Surprisingly, she forgave me, saying, 'It's okay if you just look.' From then on, whether in the bathroom or her room, I could indulge in her dense pubic hair, relying on her kindness. However, when I heard she had a boyfriend, my rationality shattered. Merely looking was no longer enough, and I finally crossed the line. This work realistically portrays the complexity of family relationships and the conflict of uncontrollable desires. Viewers will find it hard not to empathize with the protagonist's emotions.
