I See Fire : What Prince Yifan doesn't know when he saves the life of a young savage man, is that the 'savage' is actually a tribal chief's son - and that by saving his life, he enters into a vow of marriage, according to their tribe's laws.They don't even speak the same language.To say that Prince Yifan is distressed would be an extreme understatement
Weeping Willow : In which Yifan volunteers for an environmental advocacy group and Zitao is the tree he has to monitor.
♡ Virus : Yifan never had to come back. He could have taken their car and never looked back. But he had sworn a vow, on that wedding ring, on that warm smile, on those loving eyes...and although Yifan's not quite living anymore, that doesn't stop whatever is left of him from remembering. Find him. Protect him. Save Zitao.
