Shin Ha-ri (Kim Se-jeong) goes on a blind date after she agrees to replace her friend, Jin Young-seo (Seol In-ah), whose father had arranged it.

Meantime, Young-seo moves out of her father's house to escape his demands to attend blind dates and finds out, in a comic moment involving a marauding cockroach, that she is now Sung-hoon's neighbor, the man with whom she had become infatuated at first sight after meeting him at a convenience store.

[30][31] The series was created by StudioS, co-written by Han Seol-hee and Hong Bo-hee, directed by Park Seon-ho and co-produced by Kross Pictures and Kakao Entertainment.

[34] Screenwriter Han Seol-hee, better known for her work on comedy series, affirmed that what sets Business Proposal aside from other "contract marriages" storylines is its "unique sense of humour".

[36][37] In the second half of 2021, Kakao Entertainment confirmed the casting of both actors,[38][39] while Seol In-ah and Kim Min-kyu's respective agencies announced that they both would star on the show.

[52] The soundtrack album for Business Proposal, coordinated and written by music director Park Se-joon, includes 12 songs, of which ten were previously released as singles throughout the drama's airing, and 23 score pieces.

[77] On April 4, 2022, lead actress Kim Se-jeong shared a clip of her and co-star Ahn Hyo-seop singing the song together, which went viral on Twitter.

[85] The drama was particularly successful in Asia, ranking as the top series in multiple countries including Indonesia, Japan, Thailand, Vietnam, Hong Kong, Malaysia, Philippines and Singapore, while placing at number two in India and Sri Lanka, for the week of March 28 to April 3.

[87] Despite the initial concerns of adapting a webtoon into a drama,[88] Business Proposal received positive feedback for its way of embracing the clichés of the romcom genre and turning them into "slapstick comedy".

[89] Quincy LeGardye of Vulture individuated at least ten typical tropes of the romance genre used for either of the two main couples presented in the series and commented that the drama makes "smart decisions" about which to subvert and which to embrace.

While often in fiction the victim reacts "passively" and lets others handle the situation for her, in the series Young-seo reports the crime to the police and brings evidence with her.

It's also made clear that the punishment under the current South Korean law for the crime isn't enough through the words of the police officer who Young-seo speaks to.

Furthermore, in many television series', the fictional illegal recordings are frequently broadcast, usually showing the woman losing consciousness and sometimes exposing parts of her body.

After the incident, Young-seo goes through trauma and, as a result, she isn't able to use public bathrooms for fear of being filmed, showing how difficult it is for victims to overcome the pain.

With his influence as a second-generation member of a chaebol family, the male main character Kang Tae-moo manages to gather the testimonies of Young-seo's neighbor's other victims and sues him, also buying out the company where he works at and firing him.

Starring Mirror members Anson Lo and Edan Lui, the adaptation will premiere on ViuTV and on the streaming platform Viu on November 27, 2023.
