Advice???

So there's a dude at my school, lets call him Chicken. He likes me, and I know this for a fact bc he told me legit in class 😭. Idk why but i just pretended I didn't hear him, cuz i thought i misheard him or it was a prank or something. Next thing you know we're on a school trip and his friend comes up to me and says "Hey Chicken wanted me to tell you that he's still madly in love with you." I just say "what the F" and he chuckles and leaves. His other friend was literally trying to shove him into me and saying "ask her out!!!" and he replied "no!!" and ran away, clearly embarrassed asf. I'm under a lot of pressure to say yes but i'm not sure what i should say. I don't exactly have a crush on him but i also don't NOT like him, if you know what I mean. Like he's cute and nice and i feel like i could like him in the future. Something like this has actually happened to me before and I said yes, which was reeeeally the wrong thing to say lol. I have no idea wtf i should do and really need help. All my friends are like "you should say yes" but I'm kinda hesitant. Tysm and ask me anything you want if u need some clarification. Also lmk if I posted this on the wrong sub lol
