“Stop following me!” Asher yelled, his patience running thin. He had let it slide for too long because she had done a lot for him. But now she was everywhere, suffocating him.“I’m only trying to protect you,” she responded.Asher sighed, running a hand through his hair. “I need some space, alright? I can take care of myself.”She didn’t budge, and just kept staring at him with that same obsessive look, like she had no intention of leaving.“Is it because you’re strong now? Are you going to leave me because I'm no use to you anymore?” Her voice had turned cold, sharp enough to cut through the silence.“Of course not, you know that’s not the reason…”“Then why do you want me to stop following you?”“I’m just going to the restroom, for God’s sake!” He massaged his temple, clearly at his wit’s end.“Oh, you should have said that earlier.” She giggled, the earlier tension melting away.“I did,” he sighed in defeat.
