Apart from dealing with his growing feelings for Do Do Hee (Kim Yoo Jung), Jung Gu Won (Song Kang) encountered the killer and got attacked in "My Demon" Episode 7.

'My Demon' Episode 7: Jung Gu Won & Do Do Hee Start Living Like Married Couple

Jung Gu Won kissed Do Do Hee as an alibi to hide their faces from Noh Do Kyung. They felt awkward, but the kiss helped them escape being caught.

Later on, they met the mysterious woman who held secrets to their connection and told them about Gu Won's flickering powers.

The next day, the newlyweds thought about why the power flickered briefly, but they still failed to discover it.

Ju Seok Hoon's Suspects Jung Gu Won's Identity

Jung Gu Won sent all his belongings home, and Do Hee kicked him out after he protested having all of his items in the house. He waited in the car, while Ju Seok Hoon (Lee Sang Yi) visited Do Do Hee and confronted her about Gu Won's suspicious identity.

The chaebol heiress put all suspicions to rest, but Seok Hoon didn't believe her. On his way back, he invited the demon for a drink and warned him not to cause Do Hee harm.

Elsewhere, Jin Ga Yeong, who was trying to control her feelings for Gu Won, reminisced how the devil saved her from her abusive father.

Meanwhile, the stalker entered Jung Gu Won's house and placed a hidden audio recorder. He also stole the demon's guidebook with him.

Later on, Jung Gu Won returned home and recharged himself by holding Do Do Hee's wrist. The duo shared the same bed and fell asleep.

Do Do Hee Entangled in False Rumors

The next morning, they stared at each other and were conflicted about their feelings. Minutes later, Do Do Hee received a call from her assistant about the false rumors surrounding her potential killer Madam Ju for the inheritance.

The couple, along with Ju Seok Hoon, gathered at the office to resolve the issue. Seok Hoon suggested that Do Hee should open it to the board members, but Jung Gu Won advised them to solve the root of the problem.

Ju Seok Hoon left the office but soon realized that the two disappeared from the room, raising more suspicions.

Do Do Hee found out that her stepbrother Noh Seok Min was the mastermind behind the issue.

The two had a heated argument and almost shot her from the back.

The Killer Attacks Jung Gu Won

With the help of Gu Won, they were able to solve the rumors. They reached home and the demon discovered that the book was missing.

On the other hand, the stalker heard their conversation and learned Jung Gu Won's identity.

The stalker informed the killer about the demon's identity and ordered him to get rid of Gu Won first. Before the attack happened, Noh Do Kyung received a message that said, "Beginning the monster hunt."

By the end of episode 7, Jung Gu Won learned that Do Do Hee was arrested. He rushed to rescue her but the stalker stabbed him and left him unconscious.

Will Jung Gu Won survive the attack and save Do Do Hee? Let's all find out in the upcoming "My Demon" Episodes!
