Blackdream

Both dramas are BL with vampire (Nour) story where vampires have special ability and can walk under daylight. And both share the dark atmosphere.

Taiwan setting for a boylove story with identity issues even if one is because of childhood trauma and the other is wishes causing it.

Both thai BL where a police officer gets help from his soon to be student (or former student and back to be a student) boyfriend.

We have 2 thai BL drama with same level of maturity and where all ML are working adult. We also have similar trop of police officer boyfriend and obstacles to become a couple.

A celebrity coming for a reality show in one case it's in a school in the other case it's in a small town.
Adult characters (not highschool or university main leads)
BL

We have the same director as 'love in the big city'
Also this should again be a BL though not the same type of atmosphere
But still KBL + this director .... probably something serious.
