i honestly doubt y'all watched any recent dramas since many mentioned fish kisses :D they are in the past! i can make a long list to prove you wrong but let's not do that :D
i don't remember when was the last time i watched evil in-laws and a guy needs to save a girl tropes. they must have stayed in the past too. amnesia? i watched it in a recent show but it made sense (and made me furious).
to answer the question:
LOVE TRIANGLES (enough with it, ugh)
childhood connection (sometimes it does work but often is just there because why not)
fl tripping/falling and ml catching her
showing a kiss or a hug from gazillion angles (tho recently, it seems that dramas dropped this nonsense, yay!)
The let's break up even though we love each other so much (coz of some circumstance) then get when we see each other 2 years later we are still into each other and get back together + the time jump. That trope is just so lazy. Kdrama writers always use it at the end of dramas. Recent dramas it was used in includes Start Up, Record of Youth, True Beauty
do do sol sol la la sol had a time jump too. i didn't watch it tho, i dropped the show before seeing that mess (the first show i dropped at episode 14)
