Kdramas with powerful love stories, deeply in love leads.

Can you recommend powerful love stories? :) a intense, deep romance between the leads?? That thug your heartstrings, touches your heart so deeply like wow they love each other SO much , they would go to the Moon and back for each other!! They both love each other about just as much (I don’t like when one of them loves much more) basically they are each other’s whole world and cannot function well without the other, they could die for each other… no meaningless break ups please , if there is a break up the reason must be very good , not stupid reasons such as parents being against their relationship etc. . And if a break up they have to get back together again. . I don’t mind tragic (as long as it makes sense ) or happy endings, as long as the love between the leads is intense!

The one kdrama with that kind of love I seen is The Smile Has Left Your Eyes, gosh the leads were so deeply in love, they could risk it all for each other and FL even Said she cannot live without him. And ”If you die, I die too”… my heart !!

I want a unbreakable strong bond, nothing could ever tear them apart…

Any recs?? Thanks! :)
