My Girlfriend Is an Alien (2019)

Both of these dramas are similar generally. This is because:

· The female lead is from another world
· The female lead hides some things about herself from the male lead.
· The male lead is from an influential/wealthy background.
· The male lead is not interested in others but is sweet and caring with the female lead.

If you liked Legend of the Blue Sea I recommend you watching My Girlfriend is an alien

Both have a romance between an alien and a human but the genders are flipped. Both feature amnesia in some way (ML in MGIAA has an odd sort of recurring amnesia, and the FL in TEOEL forgets about the ML). Both aliens have some special power(s) that they use to help the human.

In the first season, second rate actress Tian Jing Zhi and mutant Xue Ling Qiao met because of a car accident and eventually fell in love. But to give her a peaceful and ordinary life, he decides to leave. The sequel continues this fantastical love story between human and mutant.

Not long after Xue Ling Qiao's departure, Tian Jing Zhi learns that she is pregnant. Out of concern for mother and child, Xue Ling Qiao quietly moves in next door to protect them. Meanwhile, Tian Jing Zhi befriends another mutant, Yun Zhen. Yun Zhen begins to pursue her romantically.

At the same time, the S Organization led by Qiu Yue Bai learns about Tian Jing Zhi's pregnancy. Qiu Yue Bai uses his identity as a relative to connect with her all while scheming to use her for his own gain. At the same time, a murder case that might involve mutants starts brewing as women in the city begin to disappear mysteriously.

Both are light dramas about a romance between an alien with special powers and a human.

Both MLs are CEOs with a unique medical condition that they hide otherwise they could lose their position due to scheming from family or people in the business. MLs are immune or can be treated by the FLs.

I was watching my gf is an alien after business proposal and realized some of the similarities like:
-Both male leads suffer from the rain and have a trauma linked to it
-Contract relationship between male and female leads
-Another male character likes the female (kind of a love triangle)
-Both males are rich CEO's and strong female leads works under them
-One male has a father while another has no parents
-The female lead helps solve the trauma (kind of)
-Happy endings
I think Business Proposal is more of a short, get-to-the-point than my gf is an alien.
Have a go, you might enjoy :)

My Girlfriend is an Alien says about an intergalactic romance follows an alien girl stuck on planet Earth. She crosses paths with an overbearing CEO who forgets the opposite sex whenever it rains. My Girlfriend is an Alien 2 is about Xiao Qi returning as an ambassador for her home planet, the couple embarks on another series of adventure on Earth. Hence, My Girlfriend is an Alien is the prequel of My Girlfriend is an Alien 2.

The female Lead is an Alien came from another planet that has fallen in Love with a male on Earth My girlfriend is an alien shares a similar concept to Fish Knows you as both of them are about Aliens from other planet.

Love at First Taste the boyfriend is an alien while in My Girlfriend is an alien the FML is the alien.
They both fall in love and both have something in each others body that the other needs to either be alive of go home.

These shows are similar in the fact that the male lead forgets things daily, due to something tragic happening in his past. In DJ the CEO male lead forgets everything at the end of every day but after meeting the female lead he doesn't seem to forget about her due to his feelings for her.
MGIAA is about an alien who has landed on earth, she had something taken away from her, preventing her from leaving earth. The man who stole her item is a man with a secret, due to something happening as a child, he forgets every woman he has ever met when it rains, the only person he seems to remember is our female lead.

If you liked either of them I suggest you watch the other :)

Both drama contains supernatural romantic materials.Well, even being a fantasy sci Fi "My girlfriend is an alien" basically focus over romance .Lots of kisses and sweet jealousy scenes.Also slight fantasy materials.Amounts of humor is huge.
While alongside romance and comedy Fairyland lovers contains mystery materials.Both are worth to watch

-Male Lead cannot be intimate with girls
-Only the female lead can heal him
-Cold Male lead
-Warm Female Lead

Although My Girlfriend is an alien is much more better, About is love can still quench your thirst of of fluffiness and cute romance

In both drama one partner has special ability and another one is a normal human being.In my girlfriend is an alien it's the girl who has ability and fall in with him it's the boy.
