If you want another drama with a character suffering from face blindness. This time it's ML.
Otherwise, these stories don't have much in common. When I see your face is not a fantasy drama.

Spar time period, republican era.
Same vibe with the obsessive warlord ML, misunderstanding and toxic relationship with the FL with a miscarriage, and 2FL who schemes to marry the ML, and takes advantage of a drunken night to pass for the FL that the ML is still obsessed and in love with.
Of course, no one does it better than Wallace Chung, but it’s the same mood.

Portrait of a woman in 90s China, both are stories about personal development. In both stories FL has a husband who gets in the way of the FL’s ambitions and doesn’t “deserve” her and who gets to meet a soulmate, but in Xing Fu, unfortunately, FL does not divorce… sigh..

Age gap between ML and FL, arranged marriage with a general that gradually turns into a true romance. FL is a concubine’s daughter in a family that uses her and mistreats her.

Republican era, revenge, FL has married ML’s father as a concubine and he sure ain’t happy about it.

Historical drama with the FL in a servant master relationship with the crown Prince. After a rough start, love blossoms.
Though Forbidden marriage is HE

FL is from modern world and travels to a story.
She is paired up with evil ML and ends up falling in love with him while she begins the story fearing for her life.

FL married old man in order to avenge her family and plot his death and demise.
Gets entangled with ML, her stepson, in the process.
They also used to know each other …

Réincarnation trope. Both FL commit suicide in front of Ml who they believe schemed against them. In new life they do their best to avoid ML and get a new life without trouble, but fate catches up as they inevitably get tangled up with ML.

Same pairing of older seasoned general and younger woman, daughter of a concubine, who aspires to be valued as an equal and has skills that the ML comes to respect. Same vibe of first love for an older guy.
Also same actress plays obnoxious lady trying to marry ML…

The actress is the same in both dramas. In both stories the FL infiltrates a mansion in order to get revenge after the death of her family. In both dramas, FL and ML have used to know each other and have a crush, and FL fails to recognize ML for a long time.

Same ML and FL, they had great chemistry in Love in Between. It may be nice to see them in modern setting.
