Multiple assosicates in the industry have noted that "Tayeon of Girls' Generation and Baekhyun of EXO have recently ended their relationship. The two grew distant quite naturally with their busy schedule."
Additionally they mentioned, "Taeyeon has expressed her affection for Baekhyun, even secretly attending the EXO concert in Seoul in March, but was not able to break down the wall of busy schedule. The two have broken up and have decided to remain good colleagues in their mutual agency."
translated by OP
so is exo making a come back?
SM's stance is that they're checking the validity of the news, meaning they're trying to figure out what time of day to admit it I guess.
