Memories are precious. The leads realized they are losing memories from which is out of their control. They might be gaining as much as they are losing the memories of the time spent together, but they desperately try to hold onto it by recording it down on paper.

Dramas focus on memories. One of the leads lose their memories when a specific time frame passes, forgetting who they've previously been intimately involved with. This doesn't disrupt their daily life, but it affects their relationships and ability to connect with others.

Kang Pil Jo is like reincarnation of Lin Shu. When you wacht them you have similar feeling, they always are one step above everyone. They act is always so steady, they try to hide there emotions, etc. If you love one of them, you for sure fall for the second one.

Similarities:
-Same type of female lead (cute and dumb)
-Both Female leads have an unrequited love for the Male lead at first
-Both Male leads are standoffish and highly intelligent and become doctors.
-Both SMLs blindly chase after the FLs despite the FL not liking them back.
Differences:
-ML in ALSB is less of a jerk. (but still a jerk nonetheless)
-More fluff moments in ALSB
-SLS is a little more stronger in ALSB
-ML is more friendlier in ALSB

They both have strong female leads that know what they want and are fighting for it! Both stories revolve around an office/boss - employee romance.

This is the same story but one is a movie and the other is a drama series. Both tell the story of Ja a 30(31) year old woman who is dumped after being in a relationship for about 7 years. A new love interest appears in the forms of Por.

The plot progression and the fight against the organization is somewhat similar, add to it the intelligent and smart male leads. Although the general drama vibes are different, with Chief Kim being a laugh out loud comedy. Recommend both dramas to all fans of either.

Similar business/family/ love rival drama, played out in a very well crafted story. There's lots of chemistry in this as well.

As soon as I started watching School 2017, I loved it and it reminded me a lot of Sassy Go Go....and that's when I looked it up and realized they're written by the same screenwriter!

Both are high school stories that revolve around school corruption, rich parents pressuring their students into attaining perfection, stress, violence, bullying, students with higher grades favored, power, status, etc stitched in with a romance plot both with adorable couples (if you had SLS in Sassy Go Go, then School 2017 might make you feel better since the main male lead reminds me a lot of the second lead in Sassy Go Go) The romance is very sugary/fluffy, but balanced well with the school corruption plot.

(I am definitely looking out for more of this screenwriter's works!)
(tw: suicidal subplot in Sassy Go Go)

Both of these movies have an extremely similar feel and mood to them; they're both depressing movies and moderately bloody (moderate in comparison to even more gruesome movies I mean, if you don't like the sight of blood at all don't watch either). Both revolve around children being raised as killers, but whom rebel against their "parents".

Kim Go Eun and Yeo Jin Goo are both excellent (as are the rest of the casts) but them being able to balance their roles as killers, yet still hold sympathy gets you emotional. They are both dark movies and in most ways predictable yet still thrilling. They mostly feel like the same movie to me, but genders reversed though Hwayi does have more of a deeper storyline.

The atmosphere is really common. Not the story, not the background, but the atmosphere itself, a bit dark, a bit hopeless.

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 drama stars Gong Seung Yeon. "Circle" presents an alien and "Are You Human Too" presents robot. Other similarities include a more serious approach to sci-fi which is very unique to Kdramas and the cloning subject.

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

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.
