I read this story here on dokuga in it kagome is a teen living at home and she has a sister and a baby brother i think she is dating koga in it here parents ignore her she is forced to raise her brother who i think is her sister kikyo's but she is a modle so the mom pretends he is hers. sesshomaru is her neighbor who is married with a kid. theres a part when the story when she is at his house and talking with him and kikyo comes over with the baby saying she cant take care of him.
if anyone has the slightest idea of what it could be any litle bit helps
thanks!!!
