Ok - I think there is a bit much pointless monologue, and an overuse of "ha ha ha" after several sentences. Maybe change that to a *ha ha ha*, <laughing> or something like that. Currently I imagine that the person just says "ha ha ha".
And sometimes the narrator-text is marked as MC thoughts.
Oh and when Jasmine sends the msg that you haven't send her the address, the MC still doesn't mention the meeting point, just saying that they will meet there at 16 ...
Later in the icecream shop half of a sentence from the MC is in ... Spanish or something like that.
Then at the cinema - dont know how that works in some countries, but in general you see what movie is running in the cinema before you enter the showroom....
Oh and that the MC is commenting the look of the girls is a bit -- meh? .. First that Missy girl (he says she is hot, but imho i think she is quite ugly) and in the cinema he says that Jasmine is not that hot - and that I cant support. imho she is a lot hotter than tha Missy.
Maybe add choices at both points and let the player choose - then you can use that info how to change some lines later. That doesnt have to have much impact, but I think it is a better feeling for the player.
Oh and dont just jump to the startscreen at the end without a warning. That is a no-go.
Hard to judge, it is as said just a teaser/prologue/intro and there is not much character or world building. Everything feels a bit rough and rushed. But for a first project its not so bad ^^
