I'm looking for a fic where kagome has been getting sick after the defeat of Naraku. Sesshomaru comes and explains to them that it is because she needs to travel and not be a house wife or something like that and its rated MA

That is a one shot written for the recent Fanfic Tournament... I'll look to see if I can remember which one...

Found it, I hope this is what you were looking for

Lady Almost Lost by Lyra
Rated T
Prompt: “To love someone is madness, to be loved by someone is a gift, loving someone who loves you is a duty, but being loved by someone whom you love is life.”
Synopsis: Kagome discovers that victory is not always what it seems - and that peace does not always bring relief.

Omgeee Thank you so much.!
