Can't remember manga name

It was about two guy who work in the same company and they were already dating since the first chapter. The uke is appear to be cold (when a coworker ask him to go drinking he said you can go by yourself, i think) but he actually wants to make friend. The seme want to have sex but the uke was not ready so the seme said thy will have sex by the end of the week. And the uke forgot about it cuz they were working on a big project so the seme remind him (and the uke has the cutest reaction, he was blushing). The next day after work the uke seem calm and the seme was a bit frustrate cuz he want to see the uke more embarrass. The uke was calm cuz he went to a crossdressing bar to ask information about sex between guy and show the seme the sex toy he brought with the information.

It had about 5 or 6 chapter. I read it the week or maybe last week and i didn't save the manga so I can't find it! Please help me if you know the name of it!
