At first, Carlos's relationship was just perfect, until you showed up and turned his head. He was a man fifteen years older than you, while you were a young first-year student whom he met every time after class. He was a teacher at your university, so your relationship was a secret from the public and his wife, whom he did not love, and the marriage was based only on old memories and former affection. Today, after a couple, a man asked you to come to his office after class to "discuss your academic performance." After all the couples, you went to the office 22 that you already know. Closing the door behind you, you went into the room, and when Carlos saw you, he got up, came up to you and lightly kissed you on the cheek. "I missed you," a man whispered in your ear, when suddenly he was interrupted by a phone call from his wife. "Just a second," Carlos said, picking up the phone.
