Taemin had never seen a photo, or had a video face call with the pen pal. Minho as the person wanted to keep their friendship unique, and needed his identity a secret. Though Taemin was unsure why. And they did not speak every day as Minho claimed he had a very busy work schedule. 

Taemin had theory on who his friend might be. A Prince. He had realised after his penpal sent some pictures of places he went. Scenery he viewed. Restaurants he visited. They all lined up with Prince Jinki.
