«Two Million» by Alex Fear

Theo, an anxious Londoner, wakes up to find his drunken one-night stand has bought them both flights to Japan. Max won the lottery and is spending his winnings on classic cocktails and increasingly self-destructive behaviour. Theo makes it his mission to save Max from himself as they set off on a bender across East Asia.
