How long does it take to explain the mistake by deliberately sending the wrong message to the classmates? How to explain it so as not to be seen through? What if you are really caught?

How long does it take to send a wrong message to a classmate on purpose, and how to explain it so that it won't be seen through? In this case, I don't think it is necessary to explain this. You don't need to worry about this problem. Wrong is wrong. You don't need to explain anything. This will only let it die. What do you think if he sends a message asking you? You didn't notice. Maybe you sent the wrong message, so you won't feel any embarrassment. So you don't have to explain at all, just pretend that nothing happened and you won't feel embarrassed.
