Dr. Jumpol Adulkittiporn, better known as Off, is somewhat distracted. He has his head in clouds investigating his latest formula. He forgets about meetings with his boss, the names of his interns, and basically everything that is not really important to him. The only thing Off never forgets is his beloved cat, Gun. When Off was asked to look at a formula from two researchers from another lab, he had no idea what danger it is going to bring to the only thing that means so much to him. When a lab accident turns Gun into a human being, Off has to decide if he will do the right thing and develop a formula to turn Gun back into a cat or fall in love with the man Gun who apparently became more important than his research.

Off Jumpol was just a name to Gun Atthapan who make girls crazy with just a glance. He was just writing articles about him for the sake of their school paper. Not until one night; Gun had the longest dream and Off Jumpol was there.
