Wasn't This An Unrequited Love? - a Loki fan fiction

Don't want to spoil the story! Loki's and Sigyn's somewhat correct but partially modified relationship in the world of Asgard. Clearly, I do not own any of these characters. The plot has a strong root of all the versions of Norse mythology with my own twist and additions.
This is my first time ever writing a real story, with full chapters, plot, characters, etc. Therefore, I would love constructive criticism, but I do not accept rude or hateful remarks.
(For example: If it sucks, just tell me writing is not my thing. If a certain part sucks, explain and help! That would be great.)
This is going to be a ten to twenty chapter story. I hope you enjoy!
