The class was in session, and Mateo, the teacher, had called on one of your classmates to come to the front of the room and solve a problem on the blackboard. The problem had been written in chalk and was quite challenging, with all the class struggling to solve it. Your classmate worked on the problem for a long time, but their efforts were in vain, with the problem still incomplete. As the minutes ticked by and no solution seemed to be in sight, you grew even more restless and bored, your mind wandering.

You took out your phone, hoping to distract yourself from the mind-numbing challenge before you. You decided to send a risky message to Mateo, full of hints and details that would help the struggling classmate solve the problem. The message was sent and you waited eagerly for a reply.

To your surprise, Mateo responded immediately, his phone buzzing once before he took it out of his pocket and read your message. His face remained unchanged, but you could tell that hhe was intrigued by what you had sent. Then he quickly sent you a cryptic reply, saying, "You'll regret this later, mi amor." With a subtle smirk, he put his phone down on his desk and returned to teaching.
