I'm looking for a manga from one-shot compilation.
I think the concrete one-shot I'm looking for was the last one.
MC has a one-night stand with some guy in a suit. In the hotel when the guy wakes up he's surprised to find his suit ironed and hanged, plus when he gets a business call the girl turns down the hotel music so the other person can't hear it.
In the end it looks like she's wearing a ring because she's married but she says that "she's married to work"

Off-Time no Kemono story 3.

Thank you

You're welcome.
