So since I seem to post on this page almost religiously I'd decided to wait until I had more than three fics to find, so here's a list for you guys to wrack your brains over lol XD
1) Sesshoumaru is turned into a child (I think it's by someone who meant him harm but I can't be sure), and Kagome finds him. She takes him in and they travel together, and they grow close. I also think that she wishes he could remember their time together when he goes back to normal.
2) Sess and Kag meet in the modern era, in NYC. I think they meet at some big christmas tree, and from there they start a friendship. I remember sharing hot chocolate on a bench at one point (but this could be from another fic, I sometimes get details mixed up... ^_^''). I also remember that the ending is that Kagome goes to visit the big christmas tree by herself after Sess just ups and leaves, and at the last moment just when she's about to leave, he shows up.
3) I can't remember the main plot of this sesskag story but the side story was about two star-crossed lovers. The girl died and was reborn as Rin and the guy was cursed as Jaken. Jaken tells their story to Rin, as a bedtime story I think. I also believe that they're actually soulmates? This could be another misremembered detail.
4) Kagome and gang are approached by on of sesshoumaru's men because sess has sent for kagome. He has a letter for kagome but inuyasha being who he is destroys it. She and gang travel to his citadel anyways, which is in the sky, and sess tells her that the letter said that it would probably be best for her friends to stay back on the ground.
They all meet his mother, who later stalks kagome, and when Kagome tells sess that ignoring his mother is rude, his mother calls her a good girl.
OK I think that's about it for these fics, please help me figure out which fics these are! Thanks in advance for all your effort!
