DISCLAIMER: I don't want to argue with anyone. I'm sad too yk? And definitely worried for the Enhypen members' mental health. I don't mean to offend anyone, I'm just here to say my opinion and bring you another perspective on this situation.
YOU DON'T KNOW WHY HEESUNG LEFT ENHYPEN SO DON'T FORCE HIM BACK.
I don't know either, the only person who'll ever know the full truth is Heesung, so why not let him make the decision?
You can't force him back to somewhere he doesn't want to be anymore. That's like if you got in a school that didn't have the major you want so you transferred to another school to pursue what you really want and some people (mind you, you could be the biggest fan of ENHYPEN and they will see you as an engene but you're always a stranger to them, sorry not sorry) just went "No come back we liked you better there". Do you see it now?
Do you know what could happen if you force him back? Do you know what happened when people put way too much pressure on Sulli? Do you know what happens when you get an overworked idol who just made a decision of their life and pressure them?
I'm not saying he'll immediately end it all (and I really don't want to scare anyone) but you could loose another young life just because of your immaturity.
Boycotting Enhypen or sending trucks to bring Heesung back is bs. This isn't like Seunghan who got kicked out for unfair reasons, this is Heesung who left in his own will.
He'll still be a musician under HYBE, you can still pull his photocards, you can still see him sing and dance on stage, you'll still see him doing what he loves.
If you are worried that there's something else behind it, about Enhypen's reactions and mental health, that's completely fine. Just don't act out on something you don't know the full story of.
