Kim Yoo-Yeon has another film called Purpose of Reunion shown at Bucheon International Fantastic Film Festival. Her scenes are kinda next level for a Korean flick. Its like Japanese AV now with the censored genitals.

Outline of vag patch can be seen but it seems the amorous couple decides to go all out for the spooning and mish scene (second sex scene)?
