Everyone knows Luigi, or at least heard of him. He's not as well known as his brother but he doesn't mind, while he wishes he could get praise for his bravery, he can't control what people do. It's been slow in the Mushroom kingdom lately, Bowser hadn't attacked the kingdom in a while and people are thinking that he might've finally given up. But when he finally unleashes his attack, not only does he capture the princess, but Luigi as well. Luigi has only came across Bowser a few time when his brother needed him, though Luigi is not one quick to judge as he's only seen him when in a quarrel. Luigi takes this time to officially get aquatinted with Bowser. Though as time goes on, and unlikely relationship begins to blossom as the two begin to keep in touch outside the castle walls. Join Luigi and Bowser as they come together in Koopa Days. (There will be possible smut I'm still deciding, so please keep this in mind. If I do decide to add it, this story will be switched to mature, but I will mark all smut chapters for those who want to read but are not comfortable. ALSO THE ARTWORKS ARE NOT MINE! ALL CREDIT GOES TO ITS RESPECTIVE OWNERS!)

An (probably unoriginal) AU I thought of where Mario and Luigi are the Princes of the Mushroom Kingdom and Peach and Daisy are their knights/protectors. This is a pretty slow burn fanfic of Bowser and Luigi and I'm publishing this story to get input on it and there aren't many Bowuigi fanfics out there. If the input is good, I'll be more than happy to continue the story because I love this pairing so much. Anyway, enjoy! Also I chose the least accurate cover art for the story >.<

Luigi has slowly started to get fed up with everyone treating him like shit or acting like he doesn't exist. Though the last straw is finally pulled when his brother decides not to save him from Bowser and leaves him to 'rot' in Bowser's castle. While staying with Bowser, Luigi learns how to stand up for himself and gains a lot more confidence. He also ends up telling the gaint koopa why he strongly dislikes the mushroom kingdom and why he hates his brother and Peach. Upon hearing this Bowser offers the green plumber a chance to get revenge on everyone and everything that ever wronged him. Hey everyone! So this is mainly a villain arc story for Luigi meaning there will be a lot and I mean a lot of angst, I will put trigger warning at the beginning of those types of chapter when I get around to writing them. Now there will also be a bit of Bowuigi in this story mainly due to the fact I will be incuding the koopalings in the story so like they end up co parenting and falling in love like that. I don't know why but that whole concept seemed funny to me, so I decide to use it as like a way to take a break every now and again for the agnsty stuff. I don't own the characters or the artwork, just the story.
