It was revealed today that Kim Woo Bin had sent a handwritten letter to a young female student who had revealed herself to be a huge fan of the actor before passing away in the Sewol Ferry incident. Kim Woo Bin's letter was released through an online forum through a friend of the young student. 

Kim Woo Bin wrote, "Even yesterday, I was able to finish my fan meeting in China and return well thanks to you. The place where you are right now must be a lot prettier and lovelier than here, right? After time passes and we meet again, let's take a lot of pictures and make a lot of memories. Please keep supporting me until then. I will be doing a lot of productions that we could enjoy watching when I get there. I am thankful that you are my fan. Thank you and we're sorry. Let's meet soon."
