Heat up a pan over medium heat with the cooking oil. Stir-fry the garlic for 30 seconds.

Add water, soy sauce, and hot pepper flakes. Stir it well.

Add rice syrup and stir for a few minutes until it turns a little sticky and shiny.

Add the octopus and let it sizzle for 7-8 minutes over low heat, stirring occasionally, until the seasoning liquid is almost evaporated.
