It actually started well. The light mystery and horror theme and the fact that it didn't get cute too quickly was good. However, I still couldn't avoid getting bored. The solution of the mysteries was slow and long. There were some nonsense (ex-lover, weird real estate agent and alien boy) I can't say much about this nonsense because I mostly fast-forwarded.
The chemistry of the couple was good, I expected more kissing and physical intimacy. I didn't understand why we watched their first kiss from a distance.
I understand that the ghost thing is difficult, but it is also a subject where many different things can be tried in a fantastic way. I don't understand why ghost stories are always the same things.

The clichés of ghost love dramas:
The ghost is attractive and has amnesia.
Together with the human person, they search for the ghost's past.
They always find a painful past.

For example, I think the dream thing was a good topic and could have been used much more efficiently.

I feel like writing a short ghost story.

▪ The handsome ghost of the house falls in love with the cute boy of the house and enters his dreams, where they flirt.
▪ The cute boy falls in love with the ghost. (The ghost is already in love with him.)
▪ The cute boy wants to see the ghost and ventures into the dark waters of the mystical world.
▪ Of course, there is a price for this. He opens his third eye and sees other things along with the ghost.
▪ The ghost wants to materialize and makes a deal with a shaman.
▪ As he destroys spirits that should not exist in the world, he obtains an item that allows him to materialize for a certain period.
▪ Luckily, the cute boy can now see all spiritual beings and is a human.
▪ The ghost and the human, in order to be together (and, of course, to make love), embark on a hunt in the dark world.
▪ Normally, there are many ghosts doing this job, but none do it with a human, and our ghost quickly becomes famous.
...
These are the things that come to my mind for now.

I think they shouldn't hesitate to add fantasy elements. Adding fantasy elements doesn't necessarily mean using special effects.

Other than that, it's not very memorable for me, but it's better than most ghost stories. The female character, Dream, was good. It was well developed. I liked her.
