Earlier, Chen announced the news of marriage and the second year old through a handwritten letter on the 13th.
A community EXO gallery recently posted a statement saying, "I do not support Choices of Member Chen, I feel unfair to act in the name of EXO and I demand withdrawal."
“The group EXO is a name that fans and members have kept together despite the many difficulties they have had since their debut,” they said. “Suddenly Chen’s move is selfish Choices, which not only abandons trust with fans but also feels minimal consideration for this group.”
