"It's like an undercover investigation ... Is it okay to do it? Ryo-san's girlfriend role." Our husband and wife were asked by their best friend Ryo to give up their mother who was pressing for marriage. I intended to decline, but it's a daily benefit, right? The wife was supportive and reluctant to accept the request. And a few days later, I thought that I would have a dinner at the hotel and come back soon, but it seems that Ryo's mother took care and prepared the hotel room. And at the end of the contact that I will return by the last train, my wife will not reply.
