May Tomorrow Bring Rainbows - Noriko Kihara

Whip runs a drag bar in Tokyo, where they interact with some of the most interesting people in society. But at home their days are often spent by idly chatting via a phone app with a user named "Insomniac Salaryman." Their conversations are nothing much more than grumbling about their day-to-days. So when Whip develops some light romantic feelings for this person that they have never met, they dismiss it as a romance that will never happen.
