17-year-old sophomore Xiang Wei-xin(Moon Lee) sees food as the most healing and important thing in life. That's how she meets Tao You-quan(Eric Chou): in the convenience store on campus.
When Xiang Wei-xin needs five more bucks to pay for her favorite pineapple bun, Tao You-quan chips in and saves her day. The next day, she witnesses a breakup scene by the pool in school, and it turns out to be You-quan and his cheating girlfriend who refuses to let go. Wei-xin comes up with an idea and uses her best friend/campus belle Fang Qi-ran(Jean Ho) as an excuse to intervene, ending their relationship. To her, she's returning the favor by helping out.
Since that day, Qi-ran's been receiving two breakfasts, a wooing gesture from two guys. Qi-ran is not interested and gives them to her foodie best friend Wei-xin so they don't go to waste. Wei-xin is strapped for cash, and to be able to eat to her heart's content every day is more than satisfying. Meanwhile, Zhang Yuan-shuo(Edison Song), the president of Guitar Club, uses free milk tea to get Wei-xin to say yes to do a solo show on the school's anniversary. There is only one catch: she can't really play guitar. In a chance encounter on the rooftop, You-quan offers to teach her guitar; therefore to Wei-xin, it doesn't seem like that much of a daunting challenge anymore?
Like most 17-year-old girls, Wei-xin imagines all kinds of scenarios in her future life, and You-quan, Qi-ran and Yuan-shuo do too. At the beginning of the story, they never expect so much can happen in a year and that there will be all kinds of hurdles in life?
The good news is that they eventually find the answers on their way to adulthood.
