Outside of the obvious one (Jacknaib):
- Joscarl (DMGatto, Azrael/Man in Dream, Moonlit Gentleman/Exorcist)
- Alvaluca (Warden/Winter Cicada, Paranormal Detective/Lead Consultant)
- Nightnovel (any of their matching skin combinations tbh)
- Orphnort (Orphan of Goetia/Hollow, or Default Novelist/Troubadour)

Honestly, I can't think of many more m/m ships I care about or would say I like? Ultimately I care the most about Jacknaib and Alvaluca of these ones-
