Sunshine love (2015)

Han Gil-ho wants to become a public servant, but so far has failed the civil service exam. His real interest is writing a kung-fu comic book which he has titled I'm a Public Official, featuring a crime-fighting bureaucrat and his two nerdy friends (based on himself and his slacker friends Min-gu and Park). Gil-ho then meets Kim Jung-sook, when he tags along to a meeting where she berates Min-gu into taking responsibility for her pregnant best friend Seung-hee. Gil-ho and Jung-sook realize that they knew each other years ago in college, when she was geeky and similarly hot-tempered and Gil-ho couldn't stand her. After unexpectedly sleeping together after a party, the two begin dating and eventually move in together, with Jung-sook having a regular job as a manager at a water-purifying company. Gil-ho gets an offer from a comic book publisher, but his lack of ambition and inability to commit to anything start to take their toll on their relationship.
