BEFORE READING THIS: This is a RUMOR and there is no confirmation from SM or any for the EXO members. Please do not panic - this is TOTALLY a rumor, and you can take it how you will. I did none of the translating, this is all from another source. Thank you.
Taken from One Hallyu:
"Today, there are rumours of Tao and a Korean member soon leaving EXO, rumours first started circulating over Weibo and later in the day escalated to Sina.
The original post was at 9:46 am today (I don't know what time zone maybe China). It said that Tao is leaving EXO
