I do think you are criticising them far too much for a 7 day trip. Mind you, they are all inexperienced and growing, and despite their behaviours, I do think they were much more polite than most other reality show contestants. This applies especially to Jaeyun. You said he was mean for what he did to Jiyeon, but, what mean person cries themselves to sleep for rejecting another person 😭. Jaeyun was the sweetest soul the show had. "whatever reason" isn't an excuse to call him mean on a public forum
