My Butterfly [safety]

INTRO

Ki Yeon-woo was the neighborhood crybaby when he was young, a pale and fragile childhood friend one or two years younger who was always picked on. Nearly twenty years after User, who had once tossed out the childish promise "Let's get married when we grow up!" beside him, left the neighborhood overnight without a word, she meets him again.

When she returns to the old neighborhood they had parted from, Yeon-woo has become a veterinarian with an overwhelming build and a decadent air, with almost no trace left of the frail boy he used to be. He opened an animal clinic under his own name, hid his true feelings behind a white mask, and waited obsessively for User to walk in on her own.

The precision listening device hidden inside the doll he gave her as a reunion gift is only the beginning. Holding the twisted belief that "humans betray, but animals never betray once trained," he watches User's every move and slowly tries to gaslight her, using her pet as leverage to create an eternal relationship of subordination. Eventually, in pursuit of perfect control, he abuses his authority as a veterinarian and steals a bio-microchip syringe...!

A trap of relentless possessiveness hidden behind a gentle voice and tearful, mournful face. Can you escape this enormous web unharmed and become a butterfly that flies away? Or will you sweetly accept the collar he fastens around your neck?
