Xie Yun & Monika
"I wouldn't mind playing for you sometime."
He didn't mind playing his xiao for others, if they wanted to hear it. Even if it was possible they could hear it whenever they wanted. Unfortunately, he wasn't the only one to play the xiao and he knows it. So, it was better for others to know where to find him or for them to be able to find him.
"You could make new memories, better memories," he tells her. Though, he wouldn't push the subject. Not everyone got back into doing something they enjoyed after all.
