Seo Bom dreams of becoming an adult webtoon artist, but she’s never felt a spark with real-life men. The only one who makes her heart race is her first love, Jung Taeyang, someone she’s only ever encountered in her dreams for the past eight years… until he suddenly appears in real life as the writer "Sunny"! To win an adult webtoon contest, they start living together. But Taeyang’s first blunt words catch her off guard "Is lack of experience really that important? Then why don’t you teach me, Bom?" Living together… is this really a good idea?
