No.She's laughing guys.Either his delusions are actually the truth or she's just playing with him(in that case I can assure many people in the comments will come to hate her)
you cross the road when there's green light...
is that green light or yellow light about to turn red!?
is she just playing with him or she giving a hint?
man it doesnt matter if she likes you or not in this case. Shes at least being nice to you so just try to get close to her . If she doesn't like you then who knows she might end up liking you and if she doesn't then you got a friend
