Summary

Sungyeol is hurt by something said by "so called fans" but doesn't show the boys, everyone expects him to always be his happy funny carefree bubbly self, but he can't be like that all the time after all hes human.. the people who call themselves fans said the cruel words that he read, 
he being young sometimes second guessed himself like everyone does once in a while, and also started to believe the words to be true, they referred to sungyeol not really being that needed in the group,

So the boys try & tell him to forget about it, but it bothered him a lot, days later
he then ends up overhearing woohyun make some dishearting remarks about him on accident, 
he didn't mean it in a bad way & was only teasing around like they always did as brothers,

But it goes in conjunction with the pain he already felt & becomes too much
he's not himself at all, not in the mood for anyone or anything no longer cheerful smiling sungyeol

and they notice..

Things then take an unfortunate turn when the boys are faced with a crushing situation concerning one of they're own And they find themselves putting everything into perspective..
