Since Sasori's death, Deidara was forced to stop working on missions without a partner at his side

Pain thought it would be a good idea for Tobi to be by his side, but after a few weeks a new Akatsuki arrived at the organization and everything took a 360 degree turn

He never wanted you by his side, Deidara saw you as a more unbearable nuisance than Tobi, whenever you were by his side he did everything possible not to explode you with his clay

But deep down he liked your personality although he will never say it out loud nor will he accept it openly
