Because This Is My First Life (2017)

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.

- 3 x badass female leads

- Both tackle issues of sexism

- 3 x unique perspectives of love.

- I would say BTIMFY focuses more on marriage & WWW on career BUT both explores women’s lives and the stigmas society still has.

1) Similar lighthearted vibes throughout the show
2) Cute comedic elements
3) Slice-of-life vibes
4) Mature look on relationships
5) Great chemistry between the main leads

Both drama are about a contract relationship that blooms into love and understanding. Opposites attract and life-doesnt-go-the-way-you-want-it are themes that appear in both drama.
Though BTIMFL is more of a slow paced and mature slice of life and Begin Again is more active and playful rom com, both drama couples had an amazing flow. Both drama could easily become off putting due to the plot itself but the actors in both cases did a really good job delivering their roles. You might not understand or agree with the mcs' choices so keep that in mind.

both have a marriage contract plot
both main couples have amazing chemistry and a good romance pacing

Nishimori Aoi's parents moved to another city for work, but Aoi didn't want to transfer to a new high school. She stays behind and lives in an apartment by herself. Shusei Kugayama moves in next to Aoi's apartment. Shusei is a very popular student at their high school. Due to a mistake, Aoi makes the fire sprinkler go off in his room. Until Shusei's room is fixed, he stays with Aoi.

Due to family circumstances, high school student Miko Sonoda is forced to live at her uncle's boarding house. However, before she can arrive there, Miko is already met with a bad omen: while trying to find the place, she suspects that someone is following her! When her uncle comes to her rescue, the assumed stalker happens to be one of his tenants, leaving Miko embarrassed on her first day.

Miko learns that she will be living with five unique adults, including the accused man. Additionally, it turns out that he is Jun Matsunaga, a 29-year-old designer who seems to lose his temper easily. Having made such a humiliating first impression, Miko believes that only a miserable life awaits her. But in the presence of Jun, she comes to realize that living with adults is not so difficult after all—and there may even be enough room for romance.

Has a similar contract marriage. both FML have a troubling past but it's different. Has 2nd and third couples.

Both dramas center the three long-term female friends and the plots are simple yet show a slice of life in a comedic relatable way. Both are the kind of dramas which we can cry and laugh and feel relatable at the same time. And Im jin joo and Yoon Ji Ho give off the same vibe, both are the scriptwriter and brave yet weird in some ways.

Yuki Rio, the daughter of an old, prestigious family in Kyoto with over 1,000 years of history, enters into an arranged marriage at the age of 16 with a man she’s never met. Her husband is Takamine Masatomo, a handsome CEO in the IT industry. Every year on her birthday, she would receive 50 million yen, making their relationship one based solely on money. One day, after ten years had passed with no contact, Rio decided to move to Tokyo. She asks her husband, whom she’s meeting for the first time, for a divorce. On the other hand, Takamine finds himself unexpectedly attracted to Rio and doesn’t want a divorce. Thus begins a romantic battle between a wife who wants a divorce and a husband who refuses to let her go.

Both are comforting drama! Both female leads struggled to find a new purpose in life. These drama tell viewer that it is okay to take a break from social life and to start again when ever you are ready.
