I've been dating her, Sachiko, for a year and we got engaged. We're busy preparing for our wedding and spending happy days together. One day, Sachiko went to an alumni gathering from her student club. I was worried because she said her ex-boyfriend would be there too, but she promised me she wouldn't drink too much and would take the last train home before leaving. During the party, a video sent to me showed her ex-boyfriend casually putting his arm around Sachiko's shoulder... I called her out of concern, but she was breathing heavily and said she felt sick before hanging up. That was the last time we were in contact...
