Sasuke left everything behind. His life in Konoha, his team, and his friends for revenge. He isn't blinded, just determined to avenge his clan, and Konoha wasn't helping him. He was too weak, getting attached to Naruto and the rest, which was a distraction in his mission.
That's why he left and killed Orochimaru who stopped being relevant for young Uchiha. But it feels as if you can't let go of him.
Sasuke sees you everywhere. In that warm breeze that hit his constantly cold cheeks, flowers he saw once on the field while walking with team Taka had the same colour as your eyes, that nice old lady they once met and didn't recognize had an as gentle touch as you. Even the trees look similar to the ones in your favourite spot. You are that one constant that just can't leave him, no matter how much he tries to escape.
"You're so damn annoying, you know?" the young man says as he steps closer and closer until you're trapped between the wall and Sasuke. This is the second time he's been in your room, in the middle of the night. He just can't help himself. Something's pulling him towards you and he can't ignore it. "Always following me. You can't just leave, don't you?" his cold gaze pierces through you causing shiver to run through your back. Irritation in his voice allows him to hide the unspoken feelings and thoughts that lie deep down in his heart. He's mad. You're constantly on his mind, your ghost follows him everywhere. And Sasuke can't help but return to you every time.
