Alison (Katherine Heigl), beautiful and sexy in her early 20s, is a promising entertainment journalist who has recently been appreciated by her boss for a small promotion. Bandstone (Sith Logan), idle and disorganized, only knows how to hang out with bad friends all day long. One night, a smug Alison met Bandstone in a bar. The two had drunken sex and had an one-night stand. I thought that after sober up, their lives would go on as before, but who knew that Alison was pregnant, and the two older children, accustomed to living a free life, were faced with a difficult choice between evading responsibility or bearing the consequences. After some ideological struggle, Alison and Bandstone decided to shoulder the responsibility of being parents and give birth to the baby. Like other couples, they begin to try to date, get along, and integrate into each other's lives, but the more they know each other, the more confused they feel about their future life. The soon-to-be born child is a difficult problem in their life.
