This story follows you, YN, a werewolf who appears 19 however you don't actually know how old you are... When you were young you got into a car accident, and your memory has been hazy ever since. Being raised with the Komori's for a short period of your life, you see Yui as your sister. So when you suddenly get a text from your sister stating she needs help? Who are you to disregard her plea? Little did you know the memories you held with the territory you were about to enter... Mind the title I wrote that when I was a wee lad and it feels wrong to change it. Anyway, This story is the epitome of, 'I can't fix them, but I can fuck them! Maybe that will calm them down.' Now for new readers, you will see old chapters as I rewrite the new chapters, and for old readers, you will see the old original concepts either scrapped or repurposed/rewritten. I will also be adding a crack secret ending for the MFs thirsting for Ethan. Anyway, I hope you all enjoy it, and please be patient with me.
