One of the best bittersweet movies I've seen. The premise is fairly the same of an artist (of a different genre) with a neurological condition meeting a young female student. In both stories the characters learn more about themselves and the true meaning of love and life.

Both are about criminals who take themselves too seriously (for better or worse!)

They both have comedic values in them and it involves the story and the budding romance between two childhood friends. It also portrays the process of how the childhood friends grow from not-too-successful to successful in their career paths. The similiarity between the girl main character is seen as they are both strong and rash. Although reply 1988 focuses on family values more than romantic relationships, Fight For My Way also presents the moral of family in throughout the drama. There are many other similarities between these two dramas.

If you like the way Stranger is filmed, check out Awl. It's produced by the same company & I suspect it shares the same filming crew (at least to some extent). Both have very elegant, muted colour palette consistent through a whole runtime (greener in Awl, blue to light warm brown in Stranger). Music is limited mostly to background sounds and instrumentals and it's sparsely used, OSTs come mostly in ending credits, like a MV's teaser. Flashbacks are used for the sake of the storytelling, not filling the empty spaces to meet the time limit. Both are of excellent quality.
One of the main characters in both isn't very expressive and doesn't socialise much (in Stranger he's nearly emotionless due to a brain damage, in Awl it's just a way he is: gentle and rigid).
The topics are different, but hitting similar tones and both approach them with similar attitude: showing some kind of a corruption in a broad context, as a systematic, social failure based on relationships between humans. Stranger is sexier and wittier as it takes place between Prosecutor Office and Police and involves high officials and men in power, whereas Awl's more revolting (it showcases a conflict between a labour union and a mart's foreign executives), yet both have similar down-to-earth setup and problems are solved in a realistic pace.

Both have..

-female lead involved in superstition / psychic revolations / fortune-telling
-male leads who are seriously traumatized
-logical, calculating and uninterest genius (actual genius in LR, proud in MA) male leads
-SUPER awkward side-couple
-pushy second leads

I personally prefer Lucky Romance, better cast, better storyline, more likable characters and over-all fun and an enjoyable romance.

Madame Antoine's leads had little chemistry, an unclear plot, feelings didn't feel real or important.

Both have..

-Leads enter a contract marriage (of some sort or another)
-leads start off in love with someone else
-female leads are awkward and innocent
-realistic relationships and struggles (not intense or melo-y) that are relatable
-romantic comedy that DOES NOT have an extreme melodramatic dip midway
-quickly(ish) developed cute romance
-an unavoidable occurrence causes conflict

Both dramas have..

-undercover spies that are awkward with emotional feelings
-spies end up have some relationship to an idol
-cute, fun, spunky sidekicks/side characters
-romantic relationships that affect the spies' mission
-fun comedy
-stoic male leads
-male leads' sunglasses give them an unexpected amount of personality that speaks for itself
-female leads use a friend to attract male leads' attention
-unexpected plot development
-fun, enjoyable, romancy

Both have..

-strong-willed, independent women who can fend for themselves
-female lead is proud
-female leads find themselves in unhealthy relationships
-childhood friends
-friends closer to each other than to their families
-mixing platonic feelings with romantic feelings
-characters have unfulfilling lives/jobs
-unexpected plot development (not entirely related to the whole storyline though)
-very attractive actors/actresses
-super cute and lovable romance
-100% worth your time

-includes childhood friends
-taps into career choices
-struggles of adulthood
-semi slow development

The story is different, but the feeling of both series is similar!
