Fake brother-sister relationship between the main couple (in CL both know its not true vs. LBTI where the ML knows its fake and the FL thinks he is her brother at first). Similar vibes of their relationship as well. Both are historical setting (LBTI also has fantasy elements but CL does not).

Visually impaired lead (ML vs. FL) whose sight is later restored. Both leads suffer some form of trauma and the ML is shut off from the world in a way. The main couple endure a long separation before finding their way back to each other.

Both leads have suffered loss or trauma and are distanced/cut off from society. The ML has a history of getting into fights. Both have a melancholy tone with a theme of slowly healing.

Both ML and FL suffer/have suffered loss or trauma. Both heal and slowly move forward with each others' help. The tone was similar in many ways.

The same events and time period, but one is a drama and the other a documentary. Both are very difficult to watch, but important and moving.

Similar love triangle. Many misunderstandings between the main couple.

Also in part 2 of the first season of Unique Lady, the FL agrees to go away with the SML, just like in ATWIL, but ends up returning to the ML after discovering he was wounded protecting her.

Same actor as ML. Similar historical setting, tone, and relationship between the main couple.
................................

ML has powers (shaman/sees ghosts vs. nine tailed fox) and FL is human. The couple had past lives and FL or both have now reincarnated and reunited in the present. Both couples must work to stop the powerful, supernatural villain from their past.

A quirky FL from the present day ends up in the body of a different girl in the past and has to live her life (dealing with a fiancée, etc.). Both have a fluffy, fun feel with a few serious moments.

A main character is a doctor (FL vs. ML). FL first meets the ML years before when he helps her in a situation, and then doesn't forget him during the years apart until they meet again. Their reunion, however doesn't go as FL planned at first.

Relationship between a bodyguard and the one he protects. Both are beautifully filmed, very moving, and emotional stories that have a unique and haunting tone.

Both MLs are aliens with special powers who are attempting to return home, only to decided to stay on earth, at the risk of their own lives, when they fall in love with the FL. The FL is a celebrity. Similar melancholy tone and star-crossed romance feel.
