"When a Man Falls in Love" Shin Se Kyung suddenly becomes very forward with her feelings towards Song Seung Hun.

April 11, the 4th episode of the MBC drama "When a Man Falls in Love" featured Seo Mi Do (Shin Se Kyung) going forward to hold Han Tae Sang (Song Seung Hun) in her arms when she sees him hesitating.

Seo Mi Do accidently sees Han Tae Sang's scar on his back while they are at a hotel swimming pool in Guam. She remembers an incident 7 years ago when Han Tae Sang received the scar from trying to save her. She begins to feel a mix of gratefulness and sympathy. The next day, Seo Mi Do cancels her plans with Lee Jae Hee (Yeon Woo Jin) and gets on the plane to go to Seoul.

Seo Mi Do begins to open her heart to Han Tae Sang. Her parents invite him over for dinner. Han Tae Sang is touched and says, "This is the first time eating a meal like this in 21 years." When Seo Mi Do's father asks about the reason, Han Tae Sang answers, "I lost all of my family members at the age of 17. Since then, I've been living a rough and ignorant life."

Even though Seo Mi Do's father expressed his dislike for Han Tae Sang, Seo Mi Do tried to convince her parents by saying, "He is a good person. I think he has even read more books than I have and he is extremely caring. I wouldn't be embarrassed to take him anywhere." Seo Mi Do then announces that she will continue their romantic relationship and see how things go.

In the honor of the official beginning of their relationship, Seo Mi Do and Han Tae Sang took a walk in the park nearby. Han Tae Sang wants to hold Seo Mi Do's hand but is not brave enough. Right then, Seo Mi Do grabs his hand and says, "What kind of a guy can't even hold a girl's hand?" Han Tae Sang then reveals that he has been studying about how to date online. Seo Mi Do replies, "You have a cute side."

When they are about to say goodbye, Han Tae Sang does not want to let her go yet. Seo Mi Do gets very close to his face as though she is about to kiss. Han Tae Sang hesitates and closes his eyes. Seo Mi Do makes a smart remark and laughs, teasing him.
