Meng Kerou (Guey Lun-Mei) is a seemingly average Taiwan teen who hangs out almost exclusively with pal Lin Yuezhen (Liang Shu-Hui). Their lives are filled with the usual stuff: their high school lives and boys, though the latter seems to be primarily Yuezhen's domain. Yuezhen holds a severe torch for Zhang Shihao (Wilson Chen Bo-Lin), a seventeen year-old swim team member who she simply cannot approach. Though it's rather silly, Yuezhen is simply too shy and immature to openly talk to Shihao, so she uses Kerou as an intermediary. Shihao ends up thinking that it's Kerou who has a thing for him, and not Yuezhen, who he writes off as being a fictional creation on Kerou's part. Yuezhen makes matters worse by signing a love letter in Kerou's name, and Kerou ultimately gets fed up enough to hold off on convincing Shihao of the truth. When Shihao starts to show true interest in Kerou, this can only lead to trouble.
