Oshi-sama wa Douyara Koi ga Dekinai

Komatsu Yuuri works at a pet salon and is a huge, huge fan of the incredibly popular actor Mizusawa Kai. Ever since falling for him at first sight in a drama, Yuuri’s days have been filled with work and his love for his favorite celebrity. But everything suddenly takes a turn. One day, he visits a luxury apartment for a dog-walking consultation, only to be greeted by none other than Mizusawa Kai himself. Flustered but doing his best to stay composed, Yuuri takes care of his beloved dog. Through an unexpected turn of events, Yuuri finds out that Kai is seriously considering retiring from acting for a certain reason. And the only way to stop him from doing so is for Yuuri to become his boyfriend. (Source: Sankosha, translated) Note: Includes one extra chapter.
