Sounds about right to me. I know a couple met in the similar culture camp (Taiwanese descendants went to Taipei for a summer camp and met each other there. It often turns into a dating camp for overseas youths LOL)
I did not watch the film just the trailer but maybe I will. To be fair though, that was the age this kind of the camp was aiming for (the rising, current or fresh graduated college kids), that's when my couple friends attended the camp. As to curfew... yeah weird that, unless their parents/guardians were traditional type of family... no idea.
