What's the name of this manhwa?

I'm asking for the name of this manhwa where the seme has dark blue hair while the uke has ginger or red curly hair. Story goes like this: the seme is looking for a roomate by posting an advertisement thru posters until uke sees it and grabs the opportunity instantly since he's looking for a place to stay. Fast forward, uke decided to leave the house because of how promiscuous and debauched the seme is but latter convinced him to stay and explained his side which convinced the uke to stay albeit feeling guarded around the seme. Eventually, they both fooled around and uke denied feeling good. This is as far as my brain could recall. Thank uou!ლ(´ڡ`ლ)
