Her father died when she was about 8–9 years old. She did not finish high school. At 14 she joined the adult movie business. Before that she worked at the salon of her aunt.

Kesarin was arrested by Thai police for pornographic videos released outside Thailand.^[3] These videos led to her arrest and prosecution, as pornography is illegal in Thailand.^[4] The videos featured her in hardcore porn scenes with Western and Japanese men. It was revealed that modeling and advertising companies, magazines and television programs offered her six-digit sums for modeling work since the accusation became public.^[5] She eventually had to pay a fine, received a suspended 6-month sentence, and probation for a year. Harsh punishment was avoided due to her popularity and lack of public outrage concerning her crimes.^[6]
