Group 2AM's member Im Seulong scolded a citizen for littering.

Today, Im Seulong posted on his Twitter, "You're almost home, why are you throwing this away in the elevator? You're human too so you can't be perfect but let's start by changing the little things in 2014."

In the picture that Im Seulong posted, a coffee cup and a bottled drink were sitting on the rails of an elevator.
