Inuyasha strikes me to be very irritated and full of hatred... its OOC becuase he really isnt that heartless.. plus kagome isnt attracted to koga that much... she has so many responsibilities to her future and gathering the shards she wouldnt just up and say fuck you im staying with koga... look for the rest of the shards urself. it just isnt really very like her... but its a good idea, you dont see many stories like this i suppose... everyone wants different pairings. Very angsty. (thats a good thing)
