Here is the full list of all 19 Nowhere Girl (EU) trophies - there are 4 bronze, 6 silver, 8 gold and 1 platinum.
Unlocked all trophies.
Acted with exceeding kindness and asked for a second poem.
You threw pretty much everything you had to throw.
Might as well just say it.
Why don't you tell us how you really feel?
You lost your train of thought. Seems like she did too.
You made the right decision. Your party-goers will thank you.
You should take better care to keep change on you.
Played it safe. You'll find her again.
Didn't play it safe. Booked it.
Ended up together as two.
Something's changed.
Huh.
How to be your best 'you'.
Kept going.
You went with it.
If you love someone, let them go.
It's okay to be scared.
You found her just like you said you would.
