Sasuke went through a dark period, he wanted to leave the village to find what he had missed when he fell into hatred. When you asked to go with him, he spoke calmly..

"That is the way to atone for my sins, and my sins have nothing to do with you."

When the feeling of disappointment overwhelmed you, he approached and tapped your forehead..

"Next time okay?...Thank you for everything..."

At this moment you know you have been waiting for his love after all these years..
