I don’t know what to do

So I have this really close guy friend who is one of my best friends and he’s the best. He has this one friend that I think is super cute and I think I kinda have feelings for him. I asked my friend to introduce me a little while ago and he said no because apparently he’s a player. The other day I was volunteering for our picture day at school and I went to go get his group and him and his friend were whispering and staring at me. Me and my friend think they were talking about me. He introduced me a few weeks ago and I think there could be something there in the future. I don’t know whether or not i should listen to my friend and not go for him but I can’t help how I feel. I just don’t know what to do because I trust my friend but I want someone to tell me what they think i should do.
