The link below show somebody's views that are similar to my thoughts on what totally prevented SOTKP from being…
Uhm I watched ancient love song but I think I got bored by ep4 (so didn’t bother to finish) sooo 🤷♀️ in regards of their breakup, at that time, it does seem abrupt and she shouldn’t have moved on. However, the last part it does show that as she has time to just be with your heart rather than be infatuated with the idea of being with ZZ, she would pick XW. And ZZ would fight but as he quietly observe JXN and XW, he realise he has no place in between them
Didn’t feel rush. Ending was purrrrfect!
