Did anyone else notice the post-credits sequence? It's a collection of scenes from the series tracing the progress of Ben and Jim's relationship. The voice-over seems to be Jim's. It's unclear why this was tacked on. But the real confusing thing is: the date that appears on the screen before the sequence begins is June 05, 2015. Didn't the whole story take place in the Spring of 2020?
I'm pretty sure San was 18. Thorn is 4 years older than Tharn. And Thorn and San were in the same class. I don't know about the laws in Thailand, but in the US that would be statutory rape. San has no business being anywhere near Tharn. He should be in jail.
