No one waits for rain on the Rhein, especially in Köln, where the sun always shines. Just like Sarah Köllwitz, who is living her best student life in this new city; she never wish for a rainy day. There are always things to do for herself in many different corner of this warm city. Budi Jayanto also never wish for a rain, but his first year in Köln makes him feel that every day is cloudy and his heart is rainy. But one late night encounter and another coincidental meet-up that is too cute to be true later, they learn a whole new world and a whole new feeling. Rain doesn't really bother them anymore. This is a story of two people who learn how to love from the absence of love. They try to see, understand ,and learn from each other until they understand what love needs from them and what they need from each other.
