I totally agree with you. I think the reason why Jung is like this also partially because he IS their manager and Sua bf. The line kinda get blurred there and he thinks that as he is both his manager and his bf, it's kinda up to him.
i think it is because of many reasons. like him being in love and never telling the person he fell for but running away from a huge part of himself: his sexuality. and the loss of his career because of that. i mean he worked and grew up to be an idol and bam...so now finally having someone who accepts him and expressing all his supressed desires and whatnot, i think he just clings to it, because deep down he does not feel secure yet. like it is all still relatively fresh compared to all the years of running, so i think he just needs sua to be the rock now and help him calm down haha
it is nice from him to be so concerned, but in a healthy relationship if one partner looses all sense of self like this more and more the other should remind them of themselves and that they are two separate individuals with parallel lives...i am looking forwards to sua's reaction
