According to the other tweets, this is a girl confessing to another girl.
It's because of the gender of the adjectives
Eres demasiado linda (You are too pretty)... Me pongo demasiado nerviosa (I get too nervous)
Both sender and receiver are female
I hope you like the drawing ❤
I would like to get to know you and talk with you, we can meet each other in front of the football field Friday at 11You are too pretty, I'm sorry for not being able to say this in person, but I get too nervous (maybe because of how pretty you are)
