mine so far has been the scene in the drama What's Up where tae yi and Jae-Hun are in class acting out a situation where the father diapproves of his daughter being a singer. when i saw that scence i was literally like wow they are some very good actors
this thread could get really spoilery.

my favorite sceene is from Mary stayed out all night when kang moo gyul sings hello hello at the show case. if you dont squeal just a little, you're dead inside.

i have a lot of fav. scenes but I have to mention this kiss scene from Brain. It was so intense and just cute.
Yeah I think I'll avoid this thread lol I don't see how spoilers can be avoided in ehre. XD
