The girlfriend he was engaged to was a sex friend of a rich man he didn't know... Emi Nishino
I have a girlfriend who I'm engaged to. But I happened to see it. She goes into a love hotel with an old man she doesn't know. Why on earth...! ? Even though he told me that he loved me so much... I have to ask her the truth. But I couldn't ask her about it because I was afraid of being dumped.
