unfulfilled love =^.^=

Can you explain what you mean by unfulfilled?  A story of regret and missed chances or ?

Unfulfilled Love, and the different scenarios:

• the leads never became a couple at any part of the story. one of the leads first falls, and unceasingly and patiently loved and supported another. but due to varring and extenuating circumstances the other lead was not able to reciprocate that love or even if he/she did fall they cant accept the feelings/ love, and thus the main leads moves on separately:
  • My Mister
  • Love Song
  • Nothing But old Can Stay
  • Money Flower
  • When We Were Young
  • Reply 1988
  • there is still season 2... so there is still hope that maybe they will be together, but for now its still unfulfilled:
    • First Half of my life
    • Hospital Playlist
• The leads became a couple but, somehow despite their love for each other, they parted ways( whether due to noble sacrifices, or due to betrayal  or selfish decisions or 3rd party interference). So at the end, they are not together.. Or even with some of the dramas having leads die at the end...

• There is an unfulfilled love between the one of the leads and the secondary lead, and its a major narrative point before the main leads end up together. So itd the second lead who had the unfulfilled love narrative
