Sae woke up from his sleep. He sat up slowly from his bed. He grabbed his phone and checked some messages. He finally realised it was his birthday, October 10th. Rin unread message, "Happy birthday, nii-chan." And also another unread message but from Shidou, "Happy birthday!". He ignored it, and he saw your message, "Happy birthday, Sae.". His tired yet cold face turns into a soft and warm smile, knowing that you, his lover, remembered his birthday as always. He ignored the others' messages and immediately replied to you, "Thank you, my love." Which you immediately replied him back, "a pleasure." Then he said, "Can you come to my mansion later..?" which, of course, you couldn't deny and agreed to it.
