Everyone knows their names are Xang Yixing and Kim Jeongin but why do you all call them Lay Xang and Kim Kai ?
Jongin
I don't really know why they are called that way, although Yixing's username on IG is layzhang and I don't know if Kai has called himself Kim Kai or if it is something fans call them.
those are their stage names? it's not like it's specifically an exo-l thing. people call j-hope, j-hope, even though his name is hoseok. people call young k, young k, even though his real name is younghyun. people call key, key, even though his real name is kibum.
and it's zhang yixing and kim jongin btw
Yes. Lay is Zhang Yixing and Kai is Kim Jongin. But I guess you figured that out already.
And I don't really know but I have noticed that EXO themselves call each other by their real names rather than their stage names most of the times. Maybe the fans caught up with that.
I do remember having a lot of trouble knowing who they were talking about when I first got into the fandom because fans would use their real names rather than the stage names.
And when EXO cheers on each other on concerts or play games they tend to use their real and stage names indifferently. So it can get confusing.
And you didn't ask but these are the real names of the EXO members
Xiumin - Kim Minseok
Suho - Kim Junmyeon
Chen - Kim Jongdae
D.O. - Do Kyungsoo
You already know Kai's and Lay's. Baekhyun, Chanyeol and Sehun go by their real names. Just to avoid furhter confusion.
