[All] Sungchan Chanyoung comparing arm muscles ㅋㅋ Perfect visuals including physique

Sungchan and Chanyoung keep comparing their arm muscles ㅋㅋㅋ It seems like Chanyoung in particular keeps doing that? It makes me laugh just looking at itㅋㅋㅋ

Both of them are so cute and handsome, showing off their naturally strong arm muscles that were developed through exercise. 🥹

Both of them have different styles

Because the members have really good physiques

The visual itself is already impressive

Chanyoung said he was going to lose muscle last time.. I wonder what it'll feel like haha
