I wonder why I didn't read this webtoon again. Then after reading this again, I get it now. I remember the story but not the extras. Maybe my brain want me to forget the saddest extras. It is really heartbreaking, I actually reread this again to enjoy and to relive the momment but I ended up being really sad (╯°Д °)╯╧╧
