From his debut until now, aside from the playful banter, he has always treated his fans with genuine affection and love. He is undoubtedly gentle, both to his staff, fans, and fellow members—gentle and kind.
Do those who demand Chen leave EXO under the guise of caring for them really know what 'love' is? Love is not about using the guise of doing what's best for them to insult and attack someone important to them; love is not about demanding his departure from the group in various ways; love is not what you think is doing what's best for them, nor is it moral blackmail.
What would happen if they lost one more member? Have those people thought about that? Would they still be happy? Would EXO still be EXO if one less member was there? Whether they're at their peak or not isn't the most important thing. What they want is for each other to stand shoulder to shoulder, happily looking at one another at the top. I think they're happy for Chen, because finally someone can comfort him when he's sad, take care of him when he's hurt, and guide him when he's down. Finally, someone is taking care of the always gentle Chen for us.
My understanding of love is that it should at least include: loving what they love, supporting all their choices, trusting them, supporting them, and understanding them. Because you must know that ultimately, we all need to find our own happiness.

Our Jongdae, please be happy forever, and please keep going. There are still many people who support you and like you. Please, our lead singer.
WE ARE ONE 👍🏻
