When he was formally introdued in class, he was asked to sit beside the girl whom he saw that morning. Then, their story started.

A case of dyed pink hair, an argument with la madre, and a freak encounter with an EXO member in the park after being hit in the head by a plate find Leigh Lee on a plane to Seoul the next day, with little recollection of how she got there and EXO's maknae intent on calling her hyung. She's also clutching Luhan's passport, missing her own, and widely mistaken for the second oldest boy in the group when she doesn't speak a word of Chinese. And to make matters worse, Luhan's happily waltzed off to China -- without permission and with Leigh's phone -- and expects her to fill in for him without being caught while he tries to hunt down the Mafia. "It won't be for long," he said. He needed a new dictionary.
