Because This Is My First Life (2017)

In both dramas, we have 3 bad$$ female leads and we also get three different perspectives on romantic relationships. "Because this is my first life" is more centered on marriage rather than motherhood.

There’s a similar contract style relationship with a cold male lead and a bubbly and tenacious female lead. The friends are also a mess but interesting. Suspend some disbelief because it’s not on the same level, but it did satisfy the craving for this type of dynamic.

tambem fala sobre casamento e problemas que um casal pode passar com o decorrer do tempo
é sobre um casal que se casa por conveniência mas com passar do tempo eles começam a se amar

fun, friendship based and revolve around girl friends living together. BTIMFL has more romance focus but both have similar strong female leads.

Beautiful friendships, strong females, and thought-provoking scenarios. Also, both are slice-of-life genre.

They both have to get fake married to deal with outside issues
they have in-laws that stress them out
The male lead is very protective when in-laws stress the female lead
interesting side couples
explore society's pressure on women
both living together

based on concept married first love second.also it have great story .not rick guy but slice of life at there

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

The stories are somewhat different, yet they have contract relationships in which the leads fall in love with each other.

In both shows, our main male lead is so blunt, smart, and quirky. There are some scenes when I just enjoy him talking our his logic and thoughts! He cares about his female lead and his expression shifts is very unique and endearing! I love them both! I think you can enjoy the same level of comedy from watching them interact with other characters, particularly his girlfriend.

Different but the same? Both drama are (slow-paced) slice of life stories about people in their thirties geared toward a mature, adult audience with lot of dialogue and little action and only subtle humor in between. Not office focused as FLAW is but both shows focus on a realistic, in-depth look into the definition of love, (romantic) relationships and traditional marriage as a concept in a very thoughtful and eloquent way. It also deals with topics and themes such as sexism and harrassment in the workplace, traditional gender stereotypes and its societal pressure, meddling, dysfunctional families and the generational conflict ensuing from all that etc.

The story focuses on three, very different couples, two side... one main. The romance of the main couple is slow-paced but starts from an unusual place as well, except that it is contractual, loveless marriage here instead of a passionate one-night stand turned into relationship like in FLAW. ML is the one who is cautious and afraid to get hurt again, but all the more to hurt others, introverted, but perceptive of others and logical to a fault. FL is inexperienced in love because she was too focused on work, but she is smart, a little idealistic/chaotic, headstrong and speaks her mind. Main couple also communicates well (for the most part) and deals with their conflicts in a mature, honest way. It depicts their struggle and growth needed to find a common ground for a healthy relationship together in a realistic manner, like in FLAW.

For those that can not get enough Contract Romance.
In both dramas the couples end up living together due to circumstances. In both dramas, the couples sign a contract and enter into a fake relationship. Both dramas are done well and are in my top 20 all time favorites.
The personalities of the characters is different
Because this is my first life is a little more slow paced and thoughtful. Full House has more comedy.

Their is a contract marriage.
Rich male lead
The female lead is building her career, being a writer.

Okay so they have different story
BUT!!
the feeling is same
BTIMFL is a bit more on the urban life but WTWIF is based on country side but the struggle is real (SLICE OF LIFE)
i personally liked it you watch it
