If you watched the first one you should watch the second one. It's basically a continuation from the first story.

I'm currently watching this so I can't say much but I'll be back to edit this recommendation.

I'm writing this cause I didn't like that someone didn't recommend something similar to it ?

So In first love again....his first love is reincarnated each time because of the love that connected them. So he gets reborn and reborn each time until they can be together.

In Once Again, the ML kinda like time travel? To go back to that moment he caused trauma in his first live's life.

What's similar is that if you look closely you'll notice that this isn't the first time...the ML had already travelled in time before and it's like a constant loop because eventually the Mal's "lover" would make the same choice again.

Anyway, if you like the one, you'll like the other.

Danger Zone 2 : The Sliver Lining is a continuation of Danger Zone 1.

In season 2, the story continues where they try to find the murderer and solve the mystery behind the main casts past.

Similar ghost vibes.
Finding out something that was better left untouched ?
Something in my room is a bit behind on the ghosting ?

Both dramas are office Romance.
In history 4, ting ting falls in love with his friend and both of them fear love kinda like the ml in be loved.

I don't know but I can for certain say that if you like the one, you'll love the other. I watched History 4 before Be loved so I can say with ease that both are unique in their own way.
