For Park Bo-gum, Song Hye-kyo was just a cute, sometimes weak, and human 'woman'; he began to treat Song Hye-kyo as a woman in earnest.
In the 4th episode of the TVN drama 'Boyfriend' (played by Yoo Young-ah, directed by Park Shin-woo) broadcasted on the 6th night, the romance of former chaebol daughter-in-law Cha Claudia Kim (Song Hye-kyo), free young man Kim Jin-hyuk (Park Bo-gum), and the surrounding characters Jung Woo-seok (Jang Seung-jo), Cha Jong-hyun (Moon Sung-geun), Jin Mi-ok (Nam Ki-ae), The daily history surrounding Cho Hye-in (Jeon So-ni), Nam Myung-sik (Kwon Chang-seok), Jang Mi-jin (Kwak Sun-young), Kim Jin-myung (Pyo Ji-hoon), Kim Hwa-jin (Cha Hwa-yeon), Kim Sun-ju (Kim Hye-eun), Lee Jin-ho (Kim Ho-chang), and Koo Eun-jin (Park Jin-ju) was drawn.
On this day, Jinhyuk expressed his mind without filtering to Claudia Kim and appealed to his favorite mind continuously. Claudia Kim, an adult, could not simply accept all of the hearts of Jinhyuk.
Woo Seok, who is still in a hurry to Claudia Kim, revealed to Mother Kim Hwa-jin that he does not want to live as a chaebol person and that he will live as a Jung Woo-seok. Along with this, he still felt a desire to regain Claudia Kim.
Kim Hwa-jin investigated every move around Claudia Kim, a former daughter-in-law. Hwajin has seen Jinhyuk nearing Claudia Kim, and the relationship between Jinhyuk and Claudia Kim is expected to become a crisis for the surrounding people.
Kim Hwa-jin was in contact with Cho Hye-in, Jin-hyuk's best friend. Kim Hwa-jin's aide ordered Cho Hye-in to harm Claudia Kim, but the righteous Hye-in refused to do so.
Claudia Kim was in a car accident on the road, and Jinhyuk, who saw Claudia Kim, rushed to the road and dealt with the man who was the opponent driver.
Jin-hyuk grabbed his hand, saying to Claudia Kim, who reacted sharply and sensitively, "It's like a struggle to do this." Jinhyuk walked Claudia Kim home and treated Claudia Kim as a 'woman' as a man. Jinhyuk did not forget that this was Claudia Kim's birthday, and walked him to the car and handed him a Gift.
However, Claudia Kim was saddened by the refusal to say to Jin-hyuk, "I do not want to be associated with Kim Jin-hyuk anymore, it is burdensome because it is strange." Claudia Kim was reluctant to give Jinhyuk her birthday Gift, and a man who could not push her away was shaking her daily life.
