Destiny (2021)

Both of these anthology dramas have a story where ML's significant other dies. While he initially tries to refuse giving love a second chance out of loyalty to the deceased, the deceased is still present as a ghost and is cheering the new romance on.

Thai BL dramas. Ghost Runner shares themes with the Tuesday and Thursday storylines of Y-Destiny. Running athletes (Tuesday) and Ghosts (Thursday)

Both of these BL anthologies span a variety of stories of different genres, dynamics, and worldbuilding.

The actors RamKing, who will play PerthLay in this series, are also together in My Engineer. I believe they're going to be in episode four releasing April 2nd.
Obviously, I have yet to watch Y-Destiny since it hasn't come out, but if you want a little sneak peek of their chemistry, check out My Engineer.

Has different love stories... Both series have good male leads.......... But because of you 2020 is a small bit korean drama but has a different play set which is exactly applicable on Y destiny....... In because of you there are 3 brothers and in y destiny there are 7 friends.... This is basically somewhat same relation in my eyes (friends = brothers... Only if you don't have a secret crush?)

Lay was partnered with Perth in My Engineer but was partnered with Yoon in YYY the series so it's interesting to see the three of them in the same storyline. I wonder if we will see a love triangle between the three. YYY the series is a goofy show and is the origin story of Lay and Yoon as a BL couple.

Both 7 Project and Y-destiny have multiple couples (seven couples) and they both feature some famous BL ships

Thai BL series. Hidden love main story focuses on 2 couples and the story involves ghosts. In Y-Destiny 2 storylines (Thursday and Friday) include ghosts as well.

[Recommendation for episode 9, 10 of Y-Destiny]

Both of these dramas are Thai bl romances which show two imperfect characters involved in a friends with benefits relationship, who slowly begin to fall in love with each other.

Thai BL series. The Thursday storyline in Y-Destiny is very similar to He's coming to me. Human boy and a friendly ghost fall in love.

Both Close Friend and Y-Destiny have multiple main couples with an almost equal time distribution of around 2 episodes to each couple. Also both series have similar actor pairings and including Yoonlay (great chemistry, YYY the series) and Maxnat (Dewblue from Why RU?)
