[The Please MV Storyline] It's about a guy (KHJ) seeing his ex-girl going into the house of a diff man. Hence the guy watching from the car is KHJ. But he imagined that the guy with the girl is himself and once inside the house, even with the blinds closed by the guy, he could still see their intimate actions. So he imagined himself kissing her and holding her as he watched the shadows dance behind the curtains, as he sat in the car, reliving their past memories. As he relived their happy memories (hugging, ice-cream feeding, bed-scene), it also brought him to the scene of their break-up, when he saw her not wearing their ring and he suspected she cheated on him. They broke up after that. In the song, KHJ sings that he wished the rain that nite would wash away those dark memories, as he wants her back. He regrets letting her go. That's how much he loves her, even when she cheated on him. But he knows the wish is in vain, so he finally drove away.
