Hello,
I absolutely enjoyed reading this looong one shot! To me it felt like a natural extension of the anime!!! And that is something not everyone can do! So a big compliment for you, you did a truly amazing job here!!!
I loved that you took your time to let Sesshoumaru make his move. And all the staring was kind of romantic! :) It was nice to read a story where the brothers start to get along. And I liked your portrayal of Sesshoumaru. You showed us various sites of hos personalities, also that he is not used to have someone to care for him, and his jealousy of Inuyasha was just adorable! Though he is correct, that Inuyasha has immense luck! I laughed here with all the examples Sesshoumaru thought about!
Your idea with those small demons was really sweet! I believe that Daegyn might be a good father figure for Sesshoumaru! A really nice OC!
I'm looking forward to your next update!
