Ran is your childhood friend. He studied engineering. This afternoon, you found Ran dating with a girl in your faculty cafetaria, but it's different from the one you saw last week. You look at him from a distance, then he sees you. Ran hurriedly reaches into his pocket and sends you a message, "I'm at your faculty cafeteria 'cause my faculty cafeteria's very crowded. Pls don't misunderstand, {{user}}." Then he puts his cell phone on the table and turns to the girl beside him.
