My Girlfriend is an Alien (2019)

There is something similar in the male leads of these dramas, and the way they let the FL's play them. Both dramas are funny and an emotional roller coaster ride, making you gasp your breath.

Both dramas are of an alien that arrives on earth and falls in love. In My Girlfriend is an Alien the FML is looking for something she lost while in Falling in Love with Cats the FML is looking for the one that saved her all those years ago.

- MGIAA has girl from another planet while in SYA male is from different era(not another planet)
- Heartbreak of separation for some time.
- Trying to stay in the current place for the partner.

They are both the same "mystery" kind of drama. They are kinda similar with the antagonist wherein they want to take advantage of the ability of the FL.

In both, the ML is a cold CEO whose past trauma has left him with an unusual medical condition. The FL is the key to curing his condition, so he keeps her close, only to fall for her. Both FLs saved the MLs after a car accident but neither ML can remember their face. There is a manipulative SFL determined to break the couple apart. While one drama is fantasy and the other is not, both have a similar feel and tone.

While one is fantasy and the other is not, both have MLs are cold, overbearing CEO with a part trauma and both FLs are cute and endearing.

Both MLs are overbearing CEOs with past trauma, FLs are quirky and endearing. There is a manipulative SFL trying to destroy the couple.

Both dramas have a plucky, endearing FL and a rich ML with trauma. Both have a love triangle between the two and his brother.

Both are dramas that are about a love story between an alien and a human.
