Based on my understanding, this is all about a couple who's married years ago. At first, their center of life is each other, they are happy, contented with each other until the guy felt that his wife don't care about her anymore that's why he searched love from other girls. Until one day the girl saw everything, she saw his husband kissing a girl. that broke her heart and quickly escaped the place so that his husband wouldn't know.. She never told that to her husband because she still needs him, she taught herself to ease the pain, that she will keep her mouth shut for the sake of her love to his partner. In the music video, his wife always cry because she thinks there is something missing from her her husband can't find.
