Choi Jeong Hyup is disappointed with Kim Seohyun for being as insensitive as ever and not noticing, ”Maybe it's a coincidence?”

※This article contains spoilers. Actor Choi Jeong Hyup made a mistake with his words because he felt resentful.
On the 29th night, tvN Mon-Tue TV Series "Is It a Coincidence?" EP3, Lee Ho made a mistake with his words.
Kang Hoo-young (Choi Jeong-hyeop) was depicted as having made Hong-ju (Kim Seohyun) angry. Hoo-young received a letter from his uncle Baek Wook (Choi Dae-cheol) saying that Hong-ju's former boyfriend was a high school student.
I was shocked to hear that it was Bang Junho (Yun Ji On), a novelist whom I had a passionate crush on in high school. I remembered visiting Bang Junho's unit while he was serving in the military with Hong Joo.
Hooyoung went to the military base without knowing where he was going and asked, "Are you here to visit me?" Hongju replied, "No, I came to confess my feelings. What should I do?
I'm nervous." Hooyoung was saddened to find out that Hongju had ignored him on the street and asked, "Why are you the same now as you were 10 years ago? You're still as nervous as ever.
Hong Joo was angry and said, "How dare you be so insensitive in front of other people?" and said, "I played with you all day yesterday, and today you ate chicken.
I brought you here because you said you wanted to meet Hye-ji alone, and you have no idea how well I've treated you.
"You're inconsiderate and insensitive?" I replied, "But you're the one who really pisses me off." And then I walked away.
