on the topic of your crush: don't start resenting her for not liking you. My friend had the same thing with me and he liked me for 2+ years and i was kinda jerky to him and he eventually started resenting me so much that by the time i actually grew feelings for him, we couldn't even be friends cause we kept on fighting cause he resented me so much. Don't let that happen between you two because it SUCKS.
This may not be the best explanation but if you're somewhat familiar with anime, manga is basically that but in a comic form. A mangaka/manga artist is someone who illustrates one. c:
