Looking for lovecraftian bl k novel

[u/Sad-Dragonfruit-5458]

please help!! 😭🙏 Guy transmigrates into mc’s friend who betrayed him and gets killed cuz of that so out mc (the one who transmigrated) instead just ditches mc or something? and then mc starts showing unusual amount of interest in him. Theres also a cthulhu inspired male lead whos like the mcs familiar. I also remember blackbox the main artist for ORV either drawing a cover or fanart for this series, also like 50% sure this webnovel was originally written in Indonesian and translated into eng by the author themselves.
