Before We Get Married (2019)

That is also a good drama, which is unforgettable for me. He is also toxic and selfish first. Bit later not anymore.

-Mature content and love scenes
- Similar male -lead (rich, handsome, manipulative)
-Indecisive female-lead , depends emotionally on the other person
-Love triangles

-Cheating and betrayal
-Married couple break up
-Heroine tries to deny her feelings for her new lover and avoids him by any means
-Heroine's boyfriend / husband doesn't pay any attention to her anymore

Both dramas have glimpses of the relationships of two couples before and now.. and after their so-called breaks up (as in the Before we get married no matter how insistent one of the party was.. the other didn't want to accept a break up). They have cheating in it... The actual cheating with bodies. The cheating as in the emotional sense. In both one of the exes is exploring the other for money and is being nosy about his/her new relationship.

If you like "Nevertheless" I'm sure that you're going to enjoy "Before we get married". Both have cheating in it and just toxic vibes that make you feel odd and weird, but very into it

Similar in that both FLs encounter emotional cheating temptation while they are frustrated with their long term relationships. , confused about whether they should move on with their plans to get married. Also in both, FL needs to find her backbone and voice.

Yoshino Michi is 32 years old. She's been married for five years, but hasn't had sex for the last two. It's not as if she doesn't get along with her husband, it's just that the sex part is lacking. It was a bit unexpected, but one night when she when drinking with her colleague, Niina Makoto, she wound up confessing that her marriage had turned sexless. And then, a shocked Niina responded "My marriage is sexless, too," and smiled with a lonely look in his eyes.

both have:
- fast paced romance
- includes a rich male lead

I feel like pure romance lovers will love this drama too

similar in a sense they both need to restart their lives and move on to better themselves but stuck with their current relationship due to guilt and responsibilities they put on themselves

The main male/female actor/actress are having kind of the same type of affair with each other and the feeling you get while watching Que Sera, Sera is alike and different from other dramas

Strong chemistry and feels!! Both have infidelity as main theme though on the way to airport is about married couples and loss of a loved one and is more serious.
