April: "How have you been? When I went back to school, you had already moved out of the city."
Annie: "Back then, 'Cotton' had a shorter hair style."
Evan: "Yeah, I remember."
Angel: "She looked cute."
Alfred: "She hated it. Her hair, I mean." (The commas from your baseline can be used, as well. I just thought I'd make my post a little different from the others.)
Panel 3: "What is this? It tastes great!" (That's a more literal translation: your baseline works, as well.)
Panel 6: "Guys, I think this drink has alcohol..."
April: "How have you been? When I went back to school, you had already moved out of the city." Anni
it's pretty close to what others have posted, I don't think mine is any more correct, but this is closest, in my opinion, to your original translated words.
I'll try to fix the grammar and leave as many words as possible. ----------------------------------
