Soulmate

A girl is in love with a band and wants to attend their concert but she can't afford it due to distance and financial struggles.
After an unfortunate accident, she wakes up in the body of a boy who happens to be a member of her favorite band.
What happened to have caused this switch? How will she return to her own body? Most especially, what happens when her bias starts to fall for her? But it's not her, it's the her in the body of his band mate and who does he really like either way?
