You-Jeongin
Hyunjin and Jeongin are a couple who have been dating for more than two years, but suddenly Hyunjin began to avoid any contact with him, he became uncomfortable with Jeongin. Jeongin began to notice this return from his lover, and because of this, he began to have frequent panic attacks, he was anxious all the time, and it was very difficult for him to breathe, but he did not get asthma. One day they corresponded:
Jeongin: Hey, honey, how are you? We haven't talked for a long time... do you want to come to me? Let's watch a movie together, I'll make popcorn!
Hyunjin: God, you again, I'm sick of you! Don't write to me, you annoy me! I'm uncomfortable with you.
Jeongin shuddered and cried. He didn't expect such a thing from him, so in response he wrote something like "okay" but...not quite right because of trembling hands.
Jeongin:pkau..(okay)
Will Hyunjin understand his mistake and find out how much he hurt his lover, bringing him almost to a heart attack?

Hyunjin and Jeongin are a couple who have been dating for two years, but one day Hyunjin became very cold towards Jeongin, not realizing how much he hurts him.
