Jaem and Aueng suggest to Paeng that they should go back to Bangkok but Paeng has flashbacks to Tharathep's death, resulting in a mental breakdown. Artit decides to tell Paeng that he doesn't love her. He was being kind because he feels sorry for her and that she actually loves him as a brother. But Paeng proves her love by kissing him instead.
