*This article contains spoilers. tvNTV Series "Mr. Perfect Next Door" EP9 (viewership rating: 4.5%) is about Somi's concern for the sick Sok-ryu.
When Seok-ryu gets a stomach ache and goes to the hospital with Hyun-jun, Seong-hyo is left alone and wonders what to do.
With a firm determination, he said, "It's me, Mo-eum (Kim Jieun). Tell me all the hospitals nearby that have emergency rooms," and began searching for hospitals.
After recovering, Seok-ryu is taken to the hospital where Seung-hyo's father, Kyung-jun (Lee Seung-jun), works.
When he found out he had been found out, he quickly went to the hospital to get discharged. Hyun-jun, who had been waiting for him, began to struggle to say, "Have you had a check-up? Could it have come back?", but the moment he started to speak, he was met with, "Are you okay? Are you no longer in pain? Why?
Did it hurt?" Seunghyo appeared. Hyunjun, who was astonished by Seunghyo's obvious threat, said, "You're really good at cutting in. Let's keep the line. This is Seokri.
It's just between you and me," but Seok-ryu was confused when he said, "I'm going home with Seung-hyo. We're going in the same direction. Thank you for today." "Please let me know when you get there.
"I'll wait," Hyunjun said sadly, to which Seunghyo replied, "Don't wait. I'll put this child to bed early." Hyunjun replied, "To me, Seokryu is 'this child.'
No, he's not. He's a woman." Hyun-jun was stunned, and as he watched the two of them walk away together, he remembered the first time he found out that Seok-ryu had stomach cancer.
