As we progress deeper, there is less funny and more sweet - and that impacts the gif-making. It's becoming harder. But I am not complaining. I want to cry tears of joy, that's how good this drama is.
The last scene ... it could melt a glacier.
The first gif is for cawanmerah, who asked for the one when he dances in front of Dong-Wook that stares at him blankly. Episode 3 remains by far the richest source for gifs.
