What should I do if I am confessed by my colleagues in front of the whole office?

This is really a thorny issue. After all, it's a colleague. If you don't like him, you won't want to promise yourself, and it will be embarrassing if you don't promise.

But if you like him, you can only say yes to his face. After all, it has reached this point, and it is hypocritical for you not to say yes. However, the pressure is actually great, because at the beginning, with such a high profile, both parties will hope to go for a long time, and it will be awkward to break up in the same company. Therefore, after this, you can keep a little low profile in the future, and you don't have to be so high-profile. You should know that the workplace is not a school, and the people who sincerely wish and the people who see jokes are actually half and half.

If you don't like him, in this case, you'd better not say no at once, so leave no room. You can say that this confession is too sudden, and you are not mentally prepared. Think about it before giving him an answer. Then you can ask him out to have a good talk later and tell him your thoughts euphemistically. It would be best if you could settle it all at once. If this person is very cheeky, then you can just say no next time when he makes such a high-profile confession. After all, I have already given him a face.

personally, I'm actually very embarrassed. I have a relative. At that time, he chased his ex-wife in the company with high profile, and then he got divorced after getting married for more than a year. It's really embarrassing. His ex-wife resigned directly and went back to his hometown. Therefore, people who have no confidence in office romance or who really want to keep this job should not try easily. Even if they try, they should keep a low profile and not make it public. It's better to leave a way out for themselves.
