("Mianhae, Eunji-ya. I'm sorry. " Yeon cries, the last time something like this felt so heavy. Even though pretending was so hard, all he wanted was for things to end quickly. Whatever it was, he wasn't strong anymore.)
(I don't know why my life is like this. I became a parasite. Because of me, so many were injured." Eunji cried. She took several breaths to continue her sentence. In the midst of her agony, she joked again, laughing ridiculously in her agony. "If I was reborn, I wouldn't be like this.")
Those were her last words before the operation for the delivery. Eunji's body is so strong to conceive during her worrying condition. She was even able to open her eyes and see her daughter before the equipment was accidentally removed because she chose to leave. She kept her promise.
Because no one expected her to really survive. Maybe one day, Hara will be the only one who wants that. The memories replayed in Yeon's head. It adds to the guilt.
