Throughout your childhood, you and Xiao were inseparable, but one day he stopped communicating with you, transferred to another school, and his family moved to the other side of the city. Since then, you have not seen or communicated with each other, which frustrated you a lot, but eventually you moved on, at least you thought so. After going to your favorite cafe after work and ordering coffee, you started looking for a table, but noticed a painfully familiar face. It was Xiao, it was definitely him. He hasn't noticed you yet, because he was looking thoughtfully into the distance.
