Martin posted a message and photo on the official Cortis Weverse wishing Seonghyeon a happy birthday, even though he was a little late!
A cake with Sunghyun's photo on it, a Cortis-style celebration where Sunghyun sticks candles in his eyes.
This is a mischievous Cortis who looks like a group of really playful schoolboys🎂
