SSNI-675 Class reunion NTR, married to an ex-boyfriend who used and dumped her... Tsukasa Aoi

I married Tsukasa, whom I had liked since college. At the time, she was dating a playboy named Kimura and had been cheated on and toyed with many times. I confessed my feelings to her like that, and we got married, living a smooth life. 'Kimura will come too, but don't worry,' I repeatedly declined the alumni reunion, but since our married life was going well, I let her go. Even if Kimura came, it should be fine... She was supposed to return after the first gathering, but gradually became unreachable, and even past midnight, she hadn't come back...
