Come and Hug Me

While this one seems more lighthearted in a way, Come and Hug me has the same FL lead and its crime heavy. While there is not time travel involved, I think the style and telling of these dramas are similar. Come and Hug Me is a more angsty slow burn however, I think they are pretty similar so if you haven't you could always give this one a try!

Both dramas are about two badly traumatized and emotionally fragile people who find healing in each other. Both MLs fear becoming evil and violent, both FLs are withdrawn.

Both are HEALING Slice of Life Romance Kdramas, both starring Jin Ki Joo as Female Lead.

Come and Hug Me maybe abit more melodrmatic tone than Sleeping Doctor, which going by tags seems more Comedic or maybe Dramedy.

Watch if you enjoy leads ovecome traumas and heal.

It's not exactly similar but somehow a bit part of story is similar ..The ML's father is suspect to murder FL's mother and leads are childhood sweetheart.

The dramas differ completely in terms of genre, so they give very diferent feelings (though you'll wanna hug the leads in both hehe), but they have some similar points (spoiler alert):
- A trauma in childhood that greatly affects the characters' adult life;
- Supportive families, but with some sibling (between brothers) issues;
- A solid, lovely main couple that isn't bothered by third parties. They meet when they're young, go their separe ways and only meet again as adults. They trust each other from the beginning until the ending.

Both dramas are about passing time. Both characters love only each other every time when they meet again.

Both dramas have a dark and creepy vibe and are about a serial killer connected to the past and present. Both MLs seem to have a dark side/are believed to have a dark side.
