They both fit the narrative actually. Jangmi feared the value of her existence during her highschool but chose to survive. Gukhwa feared that her existence caused pain to others but chose to stay by Jangmi after numerous struggles.
Basically, they were plagued by their existence yet chose to exist as an interdependent couple, grateful to have continued to exist.
(also, i kept repeated the title to my head when i see Gukhwa's ex and when Jae hee was being creepy and toxic HAHAHA)
I always felt that this was the two main character's saying it to each other. "It would be great if you didn't exist," then I never would have realized that I could fall in love with a woman. They both could have lived their lives as straight if they hadn't seen one another.
the title is probably describing how both couples think of themselves. they probably think they cause troubles for each other and it would be best to not exist in each others lives
Where that title come from??is it only me see the title didnt match with the story... why author put the title 'IT WOULD BE GREAT IF YOU DIDNT EXIST' because I didnt see the story from this title.
