Golf (Teerapat Lohanan Tilpat Lohanan) grew up in a broken family. He has never really enjoyed his family, so he naturally developed an unruly and irritable character. He lives in deep loneliness all day and feels that no one in the world can understand his emotions.
One day, Golf inexplicably had a Yidibank (Pongsatorn Sripinta Ponstolon Sri Pinta) four months younger than him, just because his father had a new girlfriend. Golf regarded Bank as its enemy and opponent from the beginning and was very unfriendly to him. However, the friendship between boys is so mysterious and changeable. Golf and Bank live under the same roof and share each other's happiness and sadness in a bedroom. As time goes by, they become indispensable in each other's lives.
