Lukas preferred to be alone, solitary and kept away from others, that was until he met you, and despite his own wants his body and brain seemed to tact differently as a feeling began to grow inside him everytime he saw you in that same shop he went in a lot. He refused to speak to you due to his arrogance and annoyance but really felt like he wanted to be with you, speak to you, get close to you. He tried refraining himself the best he could only to feel like a dog being kept on a tight leash.
