Similarity:
- scams
- cops find a dead body which is tied to a scammer, so they investigate them
- timeline is not fixed, it jumps around (Decoy: 3 timelines, TAoS: multiple ones)
- shows how the scammer decided to be one and built their business
- will keep you on your toes, because new evidence will make you doubt everything you knew and thought previously

Difference:
- Decoy: main scammer is a man, TAoS: a woman
- Decoy focuses more on the cop's side (present timeline), TAoS puts more focus on the scammer's becoming (victims recall past events)
- In Decoy most of the people are tied to the scam (as in took part in it and are guilty), whereas in TAoS most of them are victims and it all leads back to the FL.

Similarities:
- arranged marriage
- leads "don't like" each other at first, but grow closer over time (show their feelings better)
- couple works as a team together to get over obstacles
- clever and scheming FL and ML

Differences:
- chinese vs korean
- modern vs historical
- vibe

Overall the 2 dramas vibe is different, but I think the couple relationship and dynamics are quite similar. Both is a very good watch, they are worth to get into. (Also, I found both very binge worthy.)

Similarities:
- found family kinda vibe, with amazing chemistry between the characters, bickering, humor
- slight romance
- main story start, then focus shifts to every character's own arc centered around them, meanwhile main story still present in the background
- investigation, doing good deeds, helping others
- questionable cgi
- both are really great drama
- character's personal (backstory) drama are somewhat similar (ex. mother-daughter relationship, family drama...)

Differences:
- time line (TVIM - historical, T7ROIO - modern)
- sci-fi (T7ROIO)
- mental disorder (T7ROIO)
- revenge (TVIM)

I found the two FL's family situation quite similar, though it takes up more of the story in Autumn Fairy Tale. The topic of the last 20-ish minutes is also similar, but it would contain spoilers, so I'll just leave it at that.

Both:
- leads get to know each other in high school
- one of them leaves without a word (FL - The First Frost, ML - Ten Years of Loving You)
- FL has trouble / drama with her family
- ML is a green flag, dedicated to protect and care for the FL
- they meet again years later (TFF - 8 years later (if i remember correctly), TYOLY - 7 years later)
- living together

Both has:
- cunning FL and ML
- ML might want to kill FL at one point in the beginning of the story
- FL is no damsel in distress who need a prince
- amazing friendships and relationship dynamics
- revenge driven plot and characters
- poverty is a strong theme
- amazing actors

Difference:
- SoPG has romance, KMS has strong friendships and companionship between ML and FL
- KMS has heavier topics, SoPG is more business orientated
- more intrigues, corruption and scheming in KMS, but SoPG also has some of that, it's just not the main focus, like in KMS

- Both ML has the characteristics of animals (cat and dog)
- Leads must work together (Be my cat: to break their contract and solve a case , Husky boyfriend: to hide ML's secret while helping each other achieve their goals)
- ML and FL can't stand each other at the beginning, but throughout the story get to know each other and by the end fall in love
- Both ML's performances are awesome, especially portraying the pet behaviors

Both has:
- contract marriage
- FL hides a secret from the ML
- ML is a public figure
- A killer that is threatening the leads and tries to kill the FL to make ML suffer
- ML tries to catch the killer with his own team, not wanting to involve the police at all
- ML comes to rescue FL on multiple occasions
- Both are good (binge-worthy) dramas

FL ran away, give birth to ML's child, then comes back years later. In both dramas, the kid is sick, and the SML is a doctor, and is close to the FL (in TLYGM he has a crush on FL and is her best friend, in RF he is her ex).
