Scarlet Innocence (2014)

Scarlet Innocence (2014) is a romantic thriller that would make even greats like Hitchcock quiver. When an innocent small-town girl Deokee (Som E.) is left heartbroken by her university professor Hak-kyu (Woo-sung Jung) whom she was having a clandestine affair with, she plans her revenge. Eight years later, she finds him when he is suffering from blindness and seizes on his vulnerability to get even. She poses as his new neighbor and he has no idea that it is Deokee. 

There is nothing innocent about the golden buns on Woo-sung Jung. We get to marvel at his ass when he pulls down his underwear to have sex. We're so grateful that we aren't blind, so we can see that dumper!
