Tiffany asked fans to watch 'My Spring Day' on her brand new Instagram on September 25. She posted, "Look who came! The second guest Sooyoung," along with photos of the two in the TaeTiSeo waiting room. Tiffany added, "'My Spring Day' airs tonight at 10:30PM on MBC. Please make sure to watch it air live."
