Introduction

A stranger in a black stealth suit appeared outside the globe. He wanted Kai. They disappeared into the dust. Kai eventually returned with the stranger but he wasnt the same.

The stranger took a step towards Yeonjun with Kai's hand in his. He kissed Kai on the lips then said "he's mine now." Before Yeonjun could fight, they disappeared into the dust again. Where did Kai go and what the hell happened?
