Saint Suppapong Udomkaewkanjana was Zee Pruk Panich's worst nightmare. At high school, the wealthy and popular Saint would find ways to bully Zee. Zee would try his best to avoid any confrontations with Saint. Saint on the other hand would always find Zee anywhere he went. Nobody could touch Zee. Nobody could mess with Zee. Zee was his PET. Then, graduation came. Each went their own separate ways. Saint went studying and later living and working in the United Kingdom while Zee simply disappeared from Saint's life. Push 8 years later, Saint was summoned back to Bangkok, Thailand. He was asked to take over Arthes Technology as he had promised a family friend. Would Saint and Zee's paths cross again?
