Gong Seung-yeon is Janus with two faces.
On the latest episode of the tvN drama "Circle", the creature (Gong Seung-yeon) who visited Kim Woo-jin (Yeo Jin-goo) and Kim Beom-gyoon (An Woo-yeon) when they were young was Han Jeong-yeon (Gong Seung-yeon) the college girl in front of them today.
Twins Woo-jin and Beom-gyoon remembered their childhood like it was a horror story. They had a birthday party with the alien in front of them and had fun.
Something strange happened in a caf. A car rammed into the caf as if an alien drove it in. Beom-gyoon was in his father's arms in protection and Woo-jin was in the alien's. A shard of glass had struck the alien in the neck, but it didn't even seem to feel a thing.
