Zhang Hei didn't really remember his birthday. After all, his actual age was already over four hundred years old, and he had forgotten his exact birth date. He only remembered that his mother used to wish him a happy birthday when the temperature was very cold, and the front yard of their house was covered in a blanket of snow at that time. That was why he decided to put the date of Christmas Day on his ID card when he was living in the modern era.
Today wasn't even Christmas, and the temperature outside wasn't cold at all. The ground outside wasn't covered in snow either, and today wasn't his birthday.
However, he was very happy when Jun wished him a happy birthday while offering a sweet smile on his innocent face. It was probably the best birthday present he had ever received.
He couldn't even wipe the smile off his face as he helped Jun put on a pair of skates. His expression was different from when Jun looked restless while sitting on the bench.
