Personally for me, if they make a joke like this for once or twice I don't mind it at all but if it's this often, it would really hurt me. It is very painful if there is a friend who always make fun of someone appearance or weight which is very sensitive to a lot of people. And for them as an idols, obviously weight is something that they care about so much. And the most painful thing is that the target can't even show their emotions or get angry and just laugh like it's something funny when it's not.
I'm not accusing them of bullying Sunoo or anything like that, it's just that I'm very disappointed with the actions of the Enhypen members which are a bit too much for me in joking and I hope they can understand that this is not a good joke at all.
