It's an AU story, Sesshoumaru is Rin's father and meets Kagome when he goes to pic up Rin at her high school. Sesshoumaru then starts having a relationship with kagome without Rin finding out, eventually she does and she goes to live with her mom, who i think is Kagura. Kagome was also going to date InuYasha but Sesshoumaru interrupts them.
The title has something to do with age, for some reason the two tittles i come up with are: Age dosent matter in love and Age has nothing to do with this. However neither is giving me any results. I think i might've read the story in fanfiction.net.
