Meet these 2 girls who are sisters but not sure what is going on?

i meet both of them at the bar here, my understanding is there twin sisters however they don't really look much alike. but they are for sure sisters , i've seen there social media and they have same last name.

i'd describe both of them as fairly attractive and desirable. one might have a boyfriend and other appears to be single and on rebound.

when i first meet them i by mistake asked the one that had a boyfriend if they wanted ( other sister was with her at the time ) to do a shot with me and she said no , that was like 2 months ago

seen them a couple times since , saw the single sister at another bar a couple weeks ago , we didn't really talk but she seemed to really notice me

then last night i saw both of them again at same bar and talked to the single sister a bit , it went ok i didn't try and buy them a drink this time and then they seemed annoyed when they saw me talk to another girl there. i haven't tried to follow either on social media yet , both have private accounts so i can't even see much
