Hai <3 !! Ok this can be really confusing so basically

• Kai is from EXO Planet and he came to earth for a visit in the18th Century
• Fell in love with Yoorim and is exiled from EXO Planet
• Yoorim fell in love with him
• Yoorim dies, Kai is sad
• He wanders around earth for 300 years
• Meets Euijinand falls in love with her but Yoorim is always on his mind
• Then Nain comes into the story and Kai's confused because he doesn't love Nain but she resembles Yoorim a lot
