What did Morishima Van Gogh eat in a hamburger restaurant for three days?

Hot milk tea. In The Son of the Weather, Van Gogh Morishima survived only by drinking hot milk tea for three consecutive days. Van Gogh Morishima is the hero of the animated film Son of the Weather and its derivative works. I left my hometown for Tokyo. I met and fell in love with Amano Cai Yang, who lived alone with her younger brother, and helped Cai Yang change her fate as a sunny girl who was sacrificed to heaven. Three years later, I met Mr. and Mrs. Cai Yang again, embraced each other and bravely faced their common future hand in hand.
