Rinse cucumbers and chop into bite size moonshaped pieces.
Salt them and let sit for 5-10 minutes until water is drawn out.
Drain the cucumbers. No need to wash it, just set aside to drain.
Mix pepper flakes, sugar, fish sauce or soy sauce, sesame oil, vinegar, and garlic in a small bowl.
Add onions and paste into the cucumber and mix all together.
Garnish with sesame seeds and enjoy!
