Yonghwa is having a party in building B the curtains are open so you can watch them. Then he suddenly twitted “I love the girl from the other building” and the girl he’s referring to is Seohyun. And so he called Seohyun and start singing Love Light through the phone. It was too much for me that I was about to scream then I heard this line “Hi babe this is Kris pick up your phone yah”. Ok I’m only dreaming.
