Rain went to the CJ E&M Center to film his performance of his comeback song Love Song for M! Countdown on the 22nd. Since the morning of, he was feeling tired and fatigued. Because of his condition, he had to even get an IV shot before heading to the stage. His company said, "The filming was supposed to take place at 10 a.m. but because of his condition, it got postponed. After getting an IV shot, he went on stage at 4:30 p.m." It's great that he still persevered and managed to perform, despite the fact that he obviously wasn't feeling well. However, health is the most important so Rain should definitely get some rest if he's feeling under the weather.
