I found another letter from PCY...
Dear Baekhyun,
Hi, Baek! Can you believe that it's almost my birthday? Me either! I can't believe I'm finally turning 18! Too bad you won't be here to help me celebrate... the party is going to be great. There is going to be a cake bigger than both of our houses put together! Ha...ha, I'm kidding. But I really do miss you, Baek. Take care...
xoxo
