It's 31 Stray Kids FT. NCT Dream (occasionally ;) Supernatural Tales, one for each day of Halloween.  

The first meeting between familiar Chanyeol and witch Jongdae is electric and explosive.

Minseok leaves Jongdae and Baekhyun alone for a week (not even), praying his house will still be standing and that there will be no corpses once he returns. (It is, and there aren't)

Jooyeon just got dumped, and Chanmi hates seeing pretty girls upset.

A runaway familiar hiding a secret and an odd mix of witches, a cat familiar, and a vampire meet. Little did they know, their meeting triggers a war against a cult.

Jongdae is determined to be a helpful familiar for his adorable new master, even if Minseok is a frost mage and Jongdae hates being cold. Minseok’s cute and sweet and treats him well, so Jongdae doesn’t complain about tromping all over the snowy alpine wilderness to collect a bunch of fancy flowers and weird fungus before spring ends and time runs out. He’ll help his master break the curse, even if doing so will break Jongdae’s heart.

Warlocks and their feline familiars and one human who got caught in the supernatural.
