Kim Ji-hoon
Webtoon artist Oh Jin-rak (Kim Ji-hoon) lives in the same apartment building as Dok-mi. He has been in love with Dok-mi for ages, and anonymously leaves a carton of milk with a post-it attached by her door every day. He created a webtoon with his drawing partner Oh Dong-hoon (Go Kyung-pyo), titled "Flower Boy Next Door", based on Dok-mi's life as well as his desire to draw her out into the world.
