Sai starts to have some feelings since he defends Naruto by Karui Still BS. Sai essentially had feelings trained out of him from early childhood, and was basically emotionless during 99% of his time in Root, yet never had any issue with using the jutsu. He couldn't even find it in him to give titles to his works.
