It'S hard to rec something when you dont have your watchlist updated so i'M just gonna slap here some bromance k-dramas/movies
Hello Monster
School 2013
Shut up Flower Boy Band
Drinking Solo (the story is divided between main lead/female lead focus and then a group of 3 male friends. the main story is kinda... average but the bromance was really fun)
Midnight Runners
My Annoying Brother
No Breathing
Twenty
Laughter in Waikiki
And you might also consider checking out BL dramas since top level bromances like Guardian and The Untamed are based on BL novels anyways and are bromances only because of censorship. Thai BL dramas dont have the same high production value like c-dramas or k-dramas but they sure have certain charm about them
