Plz help me find this

This was a yaoi manga, abt a dude living alone in his messy apartment and taking a liking to the mailman and then akwardly attempts to take him hostage (he was fired from his job as a mailman so he happily said yes
And then proceeds to suck his dick thats all i remember
Also the mailman dude either had a very strong tan or is dark skinned but very lightly
Either way he has a skin tone that looks like kaeya
