Drain the golbaengi (sea snails) from the can and prepare them.

Cut the golbaengi into bite-sized pieces. Prepare the onion, chives, and green onion by chopping them.

Combine soy sauce, sugar, minced garlic, and chili powder in a pan. Simmer on low heat until the mixture starts to bubble.

Add the golbaengi pieces to the pan and stir-fry until they are well-coated with the sauce.

Add the chopped onion, green onion, and chives to the pan. Stir-fry until the vegetables are slightly softened.

Drizzle sesame oil over the mixture and stir well to combine all ingredients.

Sprinkle sesame seeds over the stir-fry for added texture and flavor.
