I don't know if I remember this fic correctly, but this is what I think I remember.

Kagome is pregnant with Sess's child and is forced back to her time. Her high school friends and Hojo find out she's pregnant and keeps asking where the father is. They're super unsupportive and say things that the father is probably a gangster like her two-timing boyfriend Inuyasha. Then at another point whenever they're leaving, and saying something negative about Sess. He appears behind her and tells them off about how they should been better friends by supporting her instead of bringing her down and kicks them out of the house.

That's all I remember from the story and I don't even know if that is 100% accurate, but I hope you guys can help me and thanks!
