As it was particularly hot last summer, the staff members had a hard time working through the sweat; therefore, T.O.P provided refreshing ice-cream.  During the colder winter times, he provided warm coffee to make the staff members feel better during filming.  His fans also helped out by providing abalone samgyetang (warm chicken broth) and buffets so the cast and crew could take care of their health and eat well. 

There were energy drinks provided in ice boxes during the hot summer days and the staff members were asked about their daily routine so customized cell phone cases and T-shirts with 'The Commitment' logos could be made and given as presents during an event.

After all the filming for 'The Commitment' was completed, T.O.P held a celebratory party at a club for the staff members who had to endure hardships throughout the lengthy production period.
