Nao Minase's coworker, Chiaki Ookawa, has a strong personality, eye-catching good looks, and secures tons of contracts because of that. It's no wonder Nao sees him as a rival, but he's also in love with him. Ever since entering the company, the two of them have had the same assignments, and their competitive personalities and constant rivalry has made people treat them like a pair. Beyond their stubbornness lies a (supposed) fondness for each other, but they're stuck in the limbo of unrequited feelings?all because they refuse to proclaim their feelings first! On the brink of that battle, a business trip sends the two men to a hotel, where love can't help but run amok! (Source: Renta!) Note: Includes 1 extra chapter.
