Shousuke had always supported his friend Tomoki, who had a tendency to fall in love quickly and suffer from heartbreak just as easily. One night, while they were drinking and Tomoki was venting about another failed romance, he jokingly professed his love for Shousuke. However, when Shousuke asked if Tomoki loved him more than his ex, Tomoki felt overwhelmed and burst into tears. In a moment of confusion, Shousuke impulsively kissed Tomoki, and thus began an unexpected relationship between a sentimental and impulsive man and a more pragmatic and cynical one. This manga also includes a bonus one-shot story entitled "The Day My Friend Disappeared".
