What should I do 😍

Alana

So there’s this new guy working in the department across my store and when I first saw him I was checking him out cause he was so cute lol and then he looked at me and we smiled and I waved at him. Then we ran into each other going up the stairs and I said hello how are you ? And he replied good and you or something like that . The next day he was talking to my supervisor about something and he was staring at me go up the stairs very seriously and I looked back for what felt like a whole minute we were locking eyes. Now he literally walks by my store and winks at me and leaves. He’s winked at me 3 times in one night. And I catch him staring at me from time to time when he walks by. Does this mean he wants to ask me out? Or sleep with me ? Should I ask my supervisor about him ? Lol or should I just keep playing his little flirting game?
