New manager trying to flirt with me !!

Okay so i just started working and this is my first job ever ! ( footlocker) Yesterday was my first day and the assistant manager was training me. we started having a conversation and he asked me if i had a boyfriend and i said no. then he said okay cause i was gonna ask for your number and i said yeah i’ll give it to you. a little while after we were in the back and he gave me his phone to put his number. after he got off that night he texted me and we were just having a regular conversation. today i was supposed to go in but he said it was moving too slow so you don’t have to come in and i was like aw man i just finished getting ready too and he replies pack “sorry babygirl i’ll make it up to you” and i ask how and he said it’s a surprise. I DONT KNOW WTF TO DO. ( everyone at the job is around the same age group) HELP ASAP because in movies and shows this never turns out to be good.
