I'm the only one who honestly enjoy the fights between Pat and Pran friends? XD they are silly exactly because they're young, yes they're in University, but they are still young boys. I don't know why people complain so much, probably you've never seen the fights in Dark Blue Kiss (same Director) lol
I bet the people complaining now saying this show is cliché, boring and childish will be the same complaining when the show will be serious and the angst will begin... just saying.
