Every Sunday, we go to the football field!
A one-time rising football star Jun-il is now only a temporal coach of a youth football center. However, he’s too hot-tempered to teach young children, now about to lose his job. Then, he receives an offer to become a coach of an amateur futsal team, FC Cheolsu. If he succeeds in making the team a finalist of Sunday Futsal League, he will be able to be a permanent coach of the center. Will he be able to grab his job with these three Mr. weirdos of FC Cheolsu?
