Along with the Kang Tae-mu and Shin Ha-ri couple, another enjoyable aspect of watching the drama “Business Proposal” is the relationship between Kang Tae-mu’s secretary, Cha Sung-hoon, and Shin Ha-best Ri’s best friend, Jin Young-seo.
The personality of Cha Sung-hoon has changed significantly since the webtoon was adapted into the drama. Furthermore, in the drama “Business Proposal,” he and Jin Young-seo interact in a very different way than they do in the webtoon.
In the webtoon, Cha Sung-hoon appears as a warm and friendly person. Kang Tae-mu asks Cha Sung-hoon to go find Jin Young-seo, whom he thought he had met on a blind date. On his boss’s orders, Cha Sung-hoon locates Jin Young-seo, and this is how he first meets her. The two have feelings for each other from their first meeting.
There is a misunderstanding in which Jin Young-seo believes Cha Sung-hoon is Kang Tae-mu, with whom she is supposed to have a blind date. Despite their miscommunication, the two go eat ramen together and have a good time chatting and smiling.
Later, Jin Young-seo discovers that Cha Sung-hoon is Kang Tae-mu’s secretary; however, she still has feelings for him.
In the drama “Business Proposal,” Cha Sung-hoon appears as a calm and logical personality to assist his boss, Kang Tae-mu. He doesn’t often smile, and he gets right to the point.
Cha Sung-hoon first meets Jin Young-seo in the convenience store, where Jin Young-seo is drawing a flower on a child’s hand.
At their first meeting, Cha Sung-hoon has a favorable impression of Jin Young-seo. However, this changes when he discovers that Jin Young-seo asked her friend Shin Ha-ri to go on a blind date for her.
The two meet each other again when Jin Young-seo moves into the apartment next door to Cha Sung-hoon. Jin Young-seo asks Cha Sung-hoon to assist her in killing the cockroaches. After being helped by Cha Sung-hoon, Jin Young-seo asks him to get along well with her since they are neighbors. On the other hand, Cha Sung-hoon rejects her friendly approach, saying, “I don’t think it’s right to be close to someone who got my boss in trouble.”
