It's the Cthulhu Mythos meets a dating simulator in Sucker for Love: First Date by indie developer Akabaka.
Play as a hapless summoner, seeking to create magic with an ancient eldritch horror that has been haunting your dreams. Or at least, that's what you thought you were doing until you came across a pink-colored Necronomicon which brought fourth three eldritch beauties instead! Playing with the dating sim tropes and twisting them into a humorous take on HP Lovecraft, Sucker for Love: First Date features a style and art direction purposefully trying to invoke old school anime dating sims, with three possible love interests and multiple endings to discover.
Sucker for Love: First Date is available on the PC.
