Good premise: quiet coworker in love with new/handsome/polite coworker and drunkely confesses after the welcome party. Unfortunately, we saw very little of the emotional build, so the intimate moments held no weight. There was a bit of build on Chii's part in a later chapter, when we got his point of view, but I wish the story had been told a little differently so I could've watched them fall in love. Pretty art, though!
