Crazy Love

Heir Goo Won, known for his brilliance and charm, despises fake smiles but is captivated by Cheon Sa Rang’s genuine one. As they bond over their shared desire for true happiness, Goo Won is thrown into an inheritance battle at King of the Land, an exclusive lounge owned by The King Group.

Cheon Sa Rang, with her radiant smile, lands a job at King Hotel, a place full of childhood memories. However, she must set those memories aside and quickly adapt to the challenges and prejudices she faces at work.

Enemies turned lovers
The leads pretend to be Engaged with a contract
Jealous and miserable Exes show up in both

Good Job is the lesser crazy version of Crazy Love.
CEOs who are more than they seem.
Company politics, office romance.
I like the FLs in both, both capable and strong.
The storylines are kinda loopy in the best kinda way.
Similar vibes really.

Love-hate relationships
MLs are rich and successful CEOs
FLs are simple girls
Contracts involving fake relationships

Contract relationships
The leads hate each other at first, but start to develop feelings
Crazy love is more of a dark comedy, while BTIMFL is more dramatic

Pontifex Rembrary, a character known for his divine powers, gets transported to a new world while fighting a devil. He possesses the body of Woo Yeon Woo, a member of an unpopular idol group, and helps turn the group's fortunes around after a disastrous live performance. With his charisma and divine powers, he becomes popular among fans but faces challenges from his past, contending with strange religious groups and the devil.

Both have similar comedy craziness and characters that pull a role to achieve their goal/revenge. Both are also underrated gems that deserve more views.

Ruri is both hardworking and beautiful. Despite everyone's assumptions, she is inexperienced with love; she has not had a boyfriend in 15 years. What will happen when her world collides with Ryo, who is "perfect in appearance and content" but continues to be shaken?

Both ML had very poor childhood but as adult they are ultra rich.
FLs are kinda personal assistance of MLs.
Both MLs appears very tough from outside but once you got to know them you realize how much of a softie they are.

The pairs have a similar dynamic, and there are a lot of similarities among the male leads..... plus the potatoes!
