G.O. wrote on his Twitter on Sunday, "With Taeng goo, for the first time in a while. We talked about stories from 8 years ago and other stories....it's fun!" He then uploaded a picture along with the tweet.
In the picture that was revealed, G.O. and Taeyeon sat side by side and looked into the camera. Taeyeon made peace signs with both her hands and smiled, and G.O. opened his eyes wide and showed his cute charms.
Internet users said, "G.O.'s face is really small," "Taeng goo for the first time in a while!," "More than lovers, they look like siblings?," "They both really look like close friends."
Meanwhile, G.O. played the role of Cyber Research Team's Lee Tae Kyun detective in the SBS Wednesday Thursday drama "Ghost."
