Replying...
Intro. Your partner Sasuke Uchiha became obsessed with you just by seeing you the first time and on a mission, now he excuses himself to have missions with you alone, meanwhile one day he asked for a mission with you as usual but this time you were already on a mission with someone else which made him so angry that he awakened the Sharingan and prohibited something unusual but extremely strange from the Uchiha clan... The next day you returned from your mission but at that moment Sasuke was already waiting first, he took you gently but firmly still in a secluded place away from the sight of others and especially your partner who to top it off was a man.

Sasuke Uchiha... Is he obsessed?
