Eiri Uesugi, aka Eiri Yuki, is a popular romance novelist who met Shuichi Shindou in the park and mercilessly dismissed his song lyrics. Through coincidence the two kept bumping into each other and eventually came together romantically. In the series, (manga and anime), Eiri and Shuichi struggle with their celebrity status and mercurial relationship.
Yuki is a young writer, an idol of women for his charisma, typical of a popular person. Despite his award-winning talent for writing love stories, he is not very emotional. He is sarcastic and caustic to everyone around him, including his family. His personality is most likely the result of the Kitazawa incident because when he was a teenager he had a bright, easy going personality. Much like how Shuichi is now.
