Please recommend dramas like The Untamed and The Legends where: one of the leads (Lead 1) dies and comes back to life years later (or is widely believed to have died for a long period of time), Lead 2 was in love with Lead 1 before Lead 1 died, and Lead 2 either continues to pine for / mourn Lead 1 for years without moving on or refuses to believe Lead 1 is dead and waits for them to return.
Bonus if Lead 2 defends / honours Lead 1's memory or looks after Lead 1's child or legacy after Lead 1's death.
