Well I am looking for a yaoi manga about this guy who was in charge of a grocery story (something like that) but one day this other guy who is from a gang tries to bully the grocery guy. The grocery guy stands up to the gang leader and instantly the leader becomes smitten with the grocery guy and pursues him.
I don't know who the mangaka is...so xD
Anyways, if you know please tell me ^^

I think you mean Secret Connection by CJ Michalski. Not grocery, but ramen shop. It's licensed, so scans are taken down from the scanlator's site, unfortunately.
