Asami posted a picture on her official Instagram in which they pose on the beach with a beautiful sunset behind them. She also thanked both his and her fans for the support and love.
She also went to describe Kubota as a man of her dreams who makes her happy.
Apparently, they started dating during the filming of drama Fugitive Boys, in which they co-starred together. Kubota played the role of a high school student while Mizukawa was his teacher, (in real life she is 5 years older than him). Shortly after, they started living together.
