Keihi de Hotel-dai wa Ochimasen!

Kikuchi takes his work as an accountant for an advertising agency very seriously—and he has secretly always been in love with Higashikaneshiro, a laid-back designer at the same firm. However, after he is outed as gay, life at the office becomes difficult. His boss is emotionally manipulative, his coworkers talk about him behind his back, and even Higashikaneshiro ends up finding out that Kikuchi is gay. All this ends with Kikuchi quitting his job. On his last day, he finds himself really wishing the day would end already... but that's when Higashikaneshiro invites Kikuchi out for a going away party, just the two of them!!
