He's Coming to Me (2019)

1. Ghost unable to reincarnate
2. Coming to terms with being in love/finding love after death
3. The same main lead; Singto

Both are ghost BL stories. A boy can see a ghost and he is the only one that can see him. The same with He's Coming to Me.

Both these works depict a gay relationship between a human and a ghost, though He's coming to me doesn't have any horror elements and is more of a mistery/rom-com compared to Sweet Curse.

Firstly, both these BLs have Ohm as the main lead. Also, even though HCTM is not about a love-to-hate romance, it does share the same theme of early childhood friends becoming more than just friends. The deepness of their relationships is what truly pulls both romances together. And a bonus is that both feature beautiful OSTs. Overall, these series are both golden BLs that you should check out!

Similar themes of the afterlife and the supernatural and human realm intersecting.
Similar themes of love and relationships

This is another outstanding BL series by GMMTV that has a mystery at its core. It is a unique story with great twists.

HCTM is an underrated drama. It has a great body of actors who deliver a great performance and story. If you are looking for a story that relies on character development and doesn't rely on gimmicks and silly tropes, then you won't regret watching this.

Both have interesting backstories! There is ghost romance in both dramas! The mysteries of why they are ghosts and their attempts to regain their memories are central to both plays.

Love the supernatural aspect of both series. The MLs also seem to have great chemistry. Very intriguing.

Both these series are supernatural tales that have a past meets present twist. Of course both are in the BL genre.

The Ghosts from both dramas cannot remember their pasts and why they died. They get to know later on in the story and why they could not go to heaven, reincarnate, etc.

Both of these dramas have "ghosts" in them.
While He She It is more vengeful than cute, they both share the plot of a ghost staying on the earth because of their death.
Both of these take place at a university, and a particular song (or songs) is important to both of their plots.

Singto is starring again in this BL drama. If that drama is about: On his birthday, Med, a kind heir to a rich family, dies mysteriously and becomes a ghost. For 20 years, he waits in the graveyard for someone to visit so that he is able to reincarnate. However, his plan for reincarnation changes completely when he spots Thun, a young boy who is able to see and talk with him during every Ching Ming Festival.
A few years pass and Thun, now a university student, reveals that Med was killed and promises to identify the reason behind Med's murder and takes Med to live with him. As they solve the issues relating to Med's death, the boys find themselves falling in love with each other despite the obvious that they must be apart one day.

Supernatural aspect is good but the chemistry between the leads is heartwarming, sad, but truly amazing

Both dramas deal with death and family. Both have themes related to relationships and deepening mystery.
