I suggest you don't meet, at least you don't have a basic understanding of him, and meeting is too rash. Homosexuality is still a sensitive group in China, and not everyone can understand and tolerate it. There are not many places in the office and the company, and there is a competitive relationship between colleagues. He works in the same company as you, so he knows too much about your private affairs and you will be extremely passive. My opinion is not to meet.
Even if office romance between men and women is taboo, what about same-sex love? Whether heterosexual or gay, it is best to avoid colleagues when looking for a partner.
