Koo Krang Kaeng Kun Keng

The story is about two strong men. Nat is fierce, he fights until the end and refuses to bend, but he has a tender heart. Pak is polite, gentle, soft, and his heart swells with the tears of a woman. They each have a girlfriend - Panumat is sweet, often paranoid, but doesn't give up easily. Sarapee is a strong and brave woman, but what her mouth says and what's inside her heart don't match. Will the two couples' love be able to get through all of their battles in life?
