Either it's not here or I'm blind but I need help, I'm trying to find this Manga, my memory is vague but here is what I remember:

The uke is having trouble with his love life and is sad or something and then suddenly the seme enters his apparent and kisses the uke, the seme thinking his the customer or something. But before things can escalate, the seme findsout he was at the wrong building and thought the uke was a customer because they had the same room number, the seme felt bad that he offers to buy the uke food and they ate at a restaurant or something. That's all I can remmeber, if you think you know the Manga, please tell me, I'd appreciate it.
