IFYLITA is one of the best Thai BLs, and one of the best BLs in general, that has been made to date and there hasn't been another one quite like it until Century of Love came along. Both of these are absolute 10s. I would recommend them both as must watches.
Waiting and searching for one you love over time is one thing both series have in common. Like UWMA, there was the nostalgic red thread or string connecting the lovers. Destny fulfilled as lovers who tie the red string to each other's finger will find each other because of being tied together. Love the reincarnation in both series as well.
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.
Supernaturally long living characters wait for the reincarnation of their long lost love who sacrificed themselves to save them. Once found, they begin love-hate relationships with the reincarnation because it is a must to lift a curse. They will literally die from the curse if they don't. A lot of long stares and awkward moments. Both are BLs.
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
