She lives in Japan and he is in the US. His father is sick and lives where OP is at.

I fly overseas annually. While there I might do additional travel in neighbour countries, I also see friends that live near location of my family. I might see them the way this guy saw BP, dinner and then maybe lunch when he is free from family obligations. I don’t fly there to see them for just one dinner. But it is the only time I might have for them.

It also could be that he was in Japan on business. Engineers from Michigan, very common to fly to japan on business. People do it all the time. He maybe ordered ton of alcohol because company pays for it. My ex flew to Japan on business, company covered alcohol at dinner time. Everyone drank because it was free. He was likely sweating due to jet lag. It’s a horrible feeling with long flight and time difference.

No way no how any man on this planet flew from Michigan to Japan just to meet a woman for dinner and lunch after talked to online for two months. Nope.
