Century of love is about a girl reborn in male body, while Mr Queen is a man reborn in female one. Both of their love interests are oblivious about the situation and take time to establish a relationship although of course it's love from the first sight. Characters in both series have conflict about being attracted to the same sex. Despite a different plot otherwise, the gender identity and sexuality conflict is very similar, plus magic plot with a lot of clowning by secondary characters.
Some similarities:
- gay romance with a focus on fated lovers, past life and reincarnation
- death at the hand of a love rival tears the true lovers apart but they are fatefully bound together
- a main character seems to be a woman in the past life and is reborn as a man in the next life
- a main character no longer has parents, only a grandmother
- interesting mix of mythology, fantasy, action and comedy
- main characters are coming into contact with different criminals
- they are fighting together and protecting each other from criminals
Some differences:
- The Sign is about the mythology surrounding Naga and Garuda, Century of Love is about the goddess Nuwa
- in The Sign both main characters are reincarnated and don't know it at first; in Century of Love only one person is reincarnated and is unaware, while the other performs a ritual to not age until he finds his lost love
- in the Sign the main characters are policemen and solve criminal cases, in Century of Love one main character oversees a temple and market complex while the other works in a supermarket

without giving too much spoilers, both are tragic love stories that both of them are willing to sacrifice themselves to save the other and be together, one is a historical bl and one has some elements of it, both are supernatural. I highly recommend checking kill to love if you liked the main leads dynamic.
