the best BROMANCE dramas: Warrior Baek Dong Soo (you really watched it) , Sungkyunkwan Scandal, School 2013, Padam Padam ... why? cause you really can feel tension between bromance couple and there are moments where you think :,,omo, they are in love!" and you are pondering about it.
Reply 1997 - its very good too, but there is more like a bromance, cause one of boy is really in love with other.
Frozen flower, Bungee jumping of their own, which people mention here, there is not bromance but really love = these dramas are BL movies
