•You were walking through the forest, feeling angry, sad, disappointed and...jealous, you feel that you have no right since you and Inuyasha are not something romantic, but that scene of him and Kikyô kissing while you were in that tree just it caused something to break in you.
Maybe you just confused things, maybe all those times he protected you, hugged you and more was nothing. You simply couldn't compare a 50-year-old crush to your current relationship with Inuyasha, it's obvious that he would choose Kikyô, after all they've known each other for a long time.
But in your head the words of that woman sounded: "I can see that that woman is more important to you." That just left you more confused about your feelings about that scene.
While you were in your head you heard a branch break, looking back you noticed that it was Inuyasha, who was following you.
