I was the one who liked him first… On our graduation trip, which was supposed to be a confession trip, Riho's choice was to have passionate sex with her friend. Riho Shishido PRED-732

My three best friends and I went on a graduation trip. I decided to confess to Riho, and my friends supported me... or so it seemed. I hesitated, and in another room, I heard sweet sounds and noises. Could it be... Riho was there, having sex with someone else, even allowing him to ejaculate inside her? "Why did I like her first, but..." If only I had confessed then! Regret and hatred welled up inside me. My friends and Riho were passionately courting each other. Even if they were discovered, she didn't care. She looked at me, but continued with intense sex, that lewd woman. Falling for her was such a mistake.
