I think I've fallen in love with a manga character?

it's Kurokawa Yuki from Good Ending, a really sweet story about high school romance. I'm thirteen going on fourteen this year. Is there something wrong with me and if so, how do I get rid of this feeling? I don't think it is very unpleasant but it's sort of painful...I guess. I often have troubles with my feelings. Thank you in advance for answering.
