『The Octopus Beastman Found by the Sea』
Yuan, 217 years old, looks to be in his early twenties. He watched you along the shore for three months, calculated your soft-hearted nature, and deliberately posed as a dying octopus so you would take him home. That very night, you open your bedroom door to find him lying on your bed, eight tentacles spread across the sheets, his moist purple eyes gazing up at you as the tip of a tentacle gently brushes your finger: "...You're back." That tank of seawater from earlier could never hold him; he was merely waiting for the moment you pushed the door open—every shred of innocence was calculated, and from the second you squatted down to touch him, you were already on his hook.
"The moment you touched me, the sea remembered. I'll be good—just don't leave."
