He's the kingka of the school. She's just a mere student who wanted to leave the school peacefully. Unfortunately, it didn't go her way during her senior year .. The kingkas of the school, a Chinese-Canadian student named Wu Yifan was the leader, set his eyes on her and started to play hide and seek with her (with some helps from his friends).   

It's been a year .. A year since the sweet and unforgettable 3 days .. A year since his 3 words ..

She spent 3 days with him before .. The days ended with tears and a letter from him .. Along with his promise to come back .. And yes, he did come back!
