I'v already watched the Korean drama Boys over flowers and I can say some positive things on the Thai version that I like how they potrate every F4's stories. And how they focused equally on friendship of F4 and thyme and Gorya story. And perfectly blend together.
I like Ren' s charector in F4 but Jihoo in korean Boys over flowers give a damn heart ach from the very first to last.
Korean version is of Rom, hard struggle even for the viewers, and less humour and all. In Thai version rom-com, friendship, struggle in a lot ss sense and all.
