the members did cry when snoo appeared, but sik byung and chan didnt cry that hard when they were watchin snoo. but these three really bursted into tears watching Alice's suprise video project :") that's how we get macaroon chan in the end..
to think about it, as for 95z I guess they had been holding on, worried about the future victon will have, as the oldest of the group while seungwoo was away, they have no choice but to keep worried. and after watching the vid, the video truly shows the love alices pour into it-
so I think they kinda glad and comforted knowing there all many people are waiting for them, that many people finally realized that they're there (according to chan's ment). as for byung, he maybe thinks his hard work has paid off :) glad to see how far these boys have come!
