Synopsis: Dulcinea-reul Wihayeo

Regretting words spoken is common, but erasing the mistake is impossible. Proverbs advise thinking carefully before speaking. However, if a time machine existed and could rectify errors, would you utilize it? Personally, I would. For instance, even if I pursued a career in music, my affections remain tied to you. How can I move on when my heart longs for you? On the other hand, when I believed our relationship ended, I allowed someone else into my heart. If I expressed a desire to return to the past, would that be heartless?
