A colleague joked to me: Another colleague likes me, and this colleague is also there, what should I do?

It can be resolved as a joke.

Jokes must be moderate and cannot embarrass the other person. It is inevitable to make such a joke among colleagues. It can be resolved in a joking way. For example, you can say: You have really good taste, and I like myself too. This way everyone can have fun without being embarrassed.

Joking, a Chinese word, means teasing, playing around, telling jokes.
