"if you want to forget, remember again." just like Geng (Arak Amornsupasiri)'s first love, he has been secretly in love with Fan (Yarinda Bunnark) since he was a student. When he plucked up the courage to confess his love, he found that he had become his best friend's girlfriend. After graduation, Geng attended their wedding, but learned of their divorce at the classmate reunion a year later. An injured dog, Geng, who runs a pet clinic, is in close contact with Fan, who loves his pet. A dusty CD makes memories that have been forgotten in the past come to mind. "if you want to remember, you forget" just like the love between Grandpa Zamula and Grandma Sompi. They met at a computer training course for the elderly on Sunday. Grandpa Zamula drove to Bangkok from Chunpeng in southern Thailand every week to be a classmate of Grandma Sompi (Sansanee Wattanakul) for three hours. Grandma Sompi's son opposed their relationship and was going to immigrate to the United States with her family, but she didn't want to leave Grandpa Zamula, so she "eloped" with Grandpa Zamula to Chunpeng without telling her son. But being tricked by fate, Grandpa Zamula's Alzheimer's disease began to slow down.
