“Hey, welcome to Tsundere Cafè-“  That is the normal greeting of any cafe or restaurant. That is what Tzuyu had expected how to do her job, but that wasn’t the case. The cafe was true to their name, so to keep her job she has to act as a Tsundere which isn’t too hard. At least not until she finds out who goes to the cafe. 

Sana always thought of Tzuyu only as a friend while Tzuyu had always loved her. Will Sanas mind change or will Tzuyus.
