Let me just break down the couples :
1. The main couple ML (Kim Ji Uk/Kim Young Dae) and FL (Shin Min Ah/Son Hae Yeong)
2. The second couple (Lee Sang Yi/Bok Gyu Hyun)and (Han Ji Hyun/Nam Ja Yeon / Yeon Bo Ra)
3. The third couple that shouldn't have existed (Joo Min Kyung/Cha Hui Seong [Hae Yeong's friend]) and (Heo Jung Min/Yun Tae Hyung)
4. I don't know if they are a ship or not but they are married so 4 couple (Jeon Hye Won/Kwon I Rin [U Jae’s wife]) and (Go Wook/An U Jae)

Let me start with the MC first I had one problem it's the fraud marriage I felt like they were trying to brainwash women into doing marriage fraud to get the advantages that come with becoming married such as a paid honeymoon/ hotel furthermore trying to make it seem like its a good idea to do a fraud marriage which is not

I have no problem with the 2nd couple it was actually the one ship that I don't mind.

I have a lot of problems with the 3rd couple like really what were the scriptwriters thinking paring up Cha Hui Seong and Yun Tae Hyung back up together it was one of the worst couple. 1st off I don't have any problem with the actor or actress of the characters I just hate the characters that they acted. One minute they in a relationship next break up and then they are in an idk what phase like honestly the character Cha Hui Seong should have stayed the single mom instead of giving a chance to Yun Tae Hyung again. IDK if they are trying to brainwash women into thinking that they need a man/father to raise a child in Korea or some shit; lets be real there is nothing wrong with a single mother can creators normalize single mother troupe it's not that hard to do. Like bruh normalize breaking up with wishy-washy guys.

Now on to the 4th couple oh dear god I don't know why the creators made the character Kwon I Rin forgive An U Jae; HOnestly, An U Jae should have never been forgiven because he cheated on both Kwon I Rin and FL (Shin Min Ah/Son Hae Yeong) IDK know why they gloss over that. Also once again felt like they were trying to brainwash women to stay with trash like really; feels like Kwon I Rin had to forgive that cheater because he was her husband or some shit like that.

I will repeat this once again I have no hate towards any actors or actresses I just hate some of the characters that is all. I really wish the 3rd and 4th couple had never existed because they don't even feel like couple feel like the woman characters were forced to be in a relationship with the male characters in both the 3rd and 4th couple. I hate how they ended the 3rd and 4th couple honestly the 3rd couple should have broken up and Cha Hui Seong never forgive Yun Tae Hyung as for the 4th couple they should have been fucking divorce . I don't understand why the character Kwon I Rin was still married to that trash An U Jae also Kwon I Rin had the upper hand because she is more financially stable than that trash husband she has,
