Are You Human Too? (2018)

One is M/F and the other BL but both are about the love story between a sweet, innocent robot and a somewhat withdraw human. Both robots are created as companions, with the creator objecting at first to the relationship. Both leads separate close to the end for several years, before a happy reunion.

Both are about artificial intelligence.
...................................................................................

Both have the lookalike takes the place of the original one trope.
But are you human too? Has a robot
and I imagine your honor has his twin brother

In both, a lookalike impersonates the "original". In School 2015, it's a twin sister, in Are You Human Too, it's a robot.

These series feature an AI as the main. The story starts a bit similarly in both as in both dramas the robot is created by a parent who misses their child.

Romance between a human and non human. Both have comedy and romance. Both are good dramas...............................

A robot named Annie started to understand the meaning of love and friendship. She eventually became a part of a family.

A drama about a school boy A Zhai. He's in love with the most beautiful girl in school, Penny. He is unable to confess his love so he brought a robot. Accidently he set the robot as Penny's ideal type instead of programming it to be Penny herself. He reorder a female robot.
But everything became complicated when the female robot started to like the male robot.

It's the second season of My Girlfriend's Boyfriend. It's a mood enlightening drama with a cute cast

SIMILARITIES:
Both explore how AI might replace human relationships/roles
Both examine ethics of AI that appears identical to actual human

DIFFERENCES:
PAtKSH = female AI AYHT = male AI
PAtKSH = AI is new character in ML life AYHT = AI is replacement for already existing character
PAtKSH = Japanese eight episodes AYHT = Korean thirty-six episodes

They are both about creating a cyborg for their personal needs, and the cyborgs living normal lives.

In both dramas ML can't feel emotions and it's the important thing that influences the plot. FL in these dramas are kindhearted, brave, independent and they fall in love with ML despite his differences and try to help ML.

The story is set in the year 2035 when a self-aware female robot enters a human family. Throughout her journey, she fights many enemies to protect her family and friends. She becomes in tune with her humanity as she grows, matures and learns about love.

In Shehong City, a man who feels that there are too many household chores buys a robot with the model "synth 2035" to help take care of his children. He names the robot An Yi. His wife is strongly against the idea and it becomes a source of their quarrels. After a while, they notice that the robot is behaving strangely. She seems like a human rather than a robot...............

The setting and atmosphere of two dramas are alike. Both contains action scenes and involved large company frauds. In "Healer", the male lead hides his real identity and pretend as someone to get the job done. In "Are You Human Too", a robot pretends to be the chaebol who is in a comatose to save his inheritance. Both use likely high technology equipment / gadgets in their mission.

Both are this ‘futuristic tech’ thingy where the ‘AI’ and ‘Robot’ have this humanism and feelings that are being called ‘bug’ and ‘error’ by them. I enjoyed it just quite fine.
