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

I married Tsukasa, whom I had loved since college. At that time, he was dating Kimura, a playboy, and was cheated on many times. I told Tsukasa about her feelings and got married, and I was living a smooth sailing life. "Kimura-kun will come too, but don't worry." Even if Kimura comes, it should be fine... I was supposed to come back from the first party, but I couldn't get in touch with him, and he didn't come back even after midnight.
