Because This is My First Life (2017)

In each drama, their is a girl with very good qualifications who ends up moving in a socially awakward -yet accomplished- man.
This living arrangement will lead to a marriage of convenience.

Similar in the fact that the drama's are very slice of life-y. The ML's are similar in a nerdy way, but the Run On ML is more of a real life take on that type of character. The FL are not that similar, but they both are strong in a not obnoxious way & are relatable. Also, the humor in both of the shows are genuinely funny & not cringe.

idk why when I started to watch Perfect and Casual, this is remind me of Because This is My First Life, for it's vibes and feelings.
ofc they are have similiarities, like:
+ Contractual Marriage, even tho the reason why they are married totally different
+ the ML is kinda of genius, quirky, and a cutie
+ the FL has their struggles with their (future) jobs, as Perfect and Casual's FL is still in college, but we'll see later

Both follow three millenial couples trying to sort out adulthood. Because This is My First Life, however, is 1000% + better. Actually has points and themes to be made regarding gender expectations, ambitions, and finding purpose in life and the value of life long friends in uncertain times.

Put Your Head on my Shoulder is the youthful, perky, cuter version of Because This is My First Life. Both dramas have similar elements (but different circumstances, mainly because BTIMFL couple are adults).

1. Cohabitation
2. A contract
3. Intellectual male lead who never treated the female lead badly
4. Cute female lead
5. Drinking beer while watching TV
6. Leads were away from each other for a while
7. Third party FL who is not annoying
8. A cat

Both dramas circle around the relationships of a group of friends. However, age of youth focuses more on friendship and Because This Is My First Life focuses on romance.

They are both about a contract marriage, marrying for living space benefits.
They end up falling in love with each other through living and spending time together.

things in common-
marriage of convenience
cohabitation
kind FLS
pretend relationship
MLS need to get a status of a married man for some reason.

Same Rom-Com aspect to both of them. The plot is somewhat similar in both of them. They both fake a marriage so the male lead can protect his house which he values a lot. The female leads are loosely similar in the way that they think of marriage the opposite way that the male leads do.

Both shows have Lee Min KI in it.
Both have similar tone: Rom-Com with a lot of heart.
Both have a contract relationship.
Both Female leads have amazing friends that support her no matter what.

in both dramas the story begins with a convention wedding. in addition to the main story, other secondary couples are presented.

Both shows are written by the same people and have a very similar feeling. They seem cute, innocent and lighthearted on the surface but address problems in society at the same time, especially concerning women’s rights. There are very progressive themes in both shows that you don’t find in most dramas. I highly recommend them both! I promise you won’t regret it :))

while watching BTIMFL, the main couple kept reminding me of cheese in the trap couple. I think they have a similar couple dynamics.

Its similar in many ways like
- the fluffiness
-the steamy kisses
- multiple couples
-contract relationship
-happy ending for all couples.

Besides that the ML is the same actor, it has the same vibe where the couple gets together under specific circumstances and with a list of rules. Pretending to date to achieve specific goals in life. It's more on the funny side, but the FL is also pretty independent, hard working and strong, but vulnerable to love.
