Hello VIPs! This song and Loser really fascinated me so I decided to write down the full meaning of this MV as I see it. I tried really hard even though I'm not a VIP. So here I go! Even though it has sexual innuendo,this MV has a deeper meaning. At the beginning, GD is dressed in those silly clothes with a backpack which represents that he is still "a child" and he just noticed the opposite sex, he sees the girl as an angel because it's his first crush. Taeyang represents the youthfull love, the beginning of a relationship, hence the cherry blossoms which actually represent how life is passable due to their short time of "living" (only 2 weeks) so could be showing young love but they wont be young like that forever. The horse is a symbol for a journey, probably life journey. TOP with the flowers; that's where love is more mature in life, when you're ready to settle down. The giant orchid actually is a symbol of pubescence (means you're mature enough for intercourse), purple roses represent enchantment and love at first sight, sunflowers represent loyalty and nourishment, and there is also some red roses which represent ofcourse love and passion. A few white roses are also there and white roses are traditional wedding flowers. So to sum it up his part represents marriage and starting a family (the baby at the end of his part). Daesung represents the time when you already settled down long ago, he is on an island and islands represent save havens, so he is "safe" with the person (the girl), they are safely connected to each other. Also, there is a palm on the island and palm trees represent peace, so they're in a peacefull time of their life journey. Sand spilling represents the time passing by. And then we come to Seungri, and first he lights a match, fire represents fear and destruction, it could be a symbol for the end of the journey and fear of death. He and the girl also have white hair which means that they have finished their life journey together. And the purple rose withering is ofcourse death. After that they're all flying over the moon, and the moon is a symbol for rhythm of time and also the symbol of the soul, which means when your time is done your soul leaves for heaven (or whatever you believe in). While rice represents fertility, it also represents a connection between the Earth (man) and heaven (God, or something else you believe in), so at the end it's them enjoying their afterlife.
Hope I didn't miss anything or bore you with this long explanation, I just love their new songs so much^^
