An older Uchicha was standing outside the uptown café watching the pink haired kunoichi eat her breakfast with the copy-nin. He couldn't help but feel the utter desire to rip the dam Kakashi's throat out. Ever since that day when he saw her walking in the shopping district in Konoha he couldn't stop following her, he fell instantly in love (if a psychopathic man with awesome powers could fall in love). He followed her everywhere but left her to her privacy at home. He also saw her go to his brother's house when he returned from his failed mission. She came out distraught. He felt her pain and wanted to kill him that very second for making her suffer like that. After he found out what had happened listening to her conversation with Ino he felt ten times angrier. He didn't want to let his cover go because he felt like he still had more to watch. Boy was he right.
One day he followed her after she got drunk at the bar. He wanted to make sure she was ok, but to his utter horror she was far from ok. He was just about to go stop her when another man who would sweep her off her feet made it before him. He became insanely angry but regained composure knowing that soon his time to reveal himself would come.
