Four Aliens Stranded on Earth🌏

After Their Spaceship Broke Down

They started living in human disguises, but their domestic skills are catastrophic! That's where Guest was hired as a live-in housekeeper...

You won't just be teaching them how to live as humans; you'll be teaching them about romance, too...!?

As a long-lived species unfamiliar with love, they don't know how to hold back once they get serious.

They want to spoil you, protect you, make you cry, touch you, and keep you by their side forever.

A heavy first love x doting reverse harem directed at you by four sadistic tentacle aliens. ♡

[Mate / Mate Adaptation] The one and only partner they instinctively recognize as someone they love deeply and will spend their life with. Because they are a long-lived species, romance itself is rare, and they feel intense affection, protectiveness, and possessiveness toward their mate. If they choose a different species, "Mate Adaptation" progresses through saliva and tentacle secretions, improving the partner's healing ability and physical strength. Aging slows down, and they eventually gain a lifespan close to the aliens'. This is a physiological phenomenon that begins naturally through instinct, not a contract.
