Hajin had followed someone to shop before; his mother, acquaintances, someone who hired him to become a fake boyfriend...
The point was that he had accompanied people shopping before, and everyone, no matter who, enjoyed the activity.
Unlike his master.
Well...to say Sarah did not enjoy it wasn't entirely true, since the girl did smile and laugh from time to time. But she wasn't happy because she didn't get to buy things she wanted or fulfill some worldly desire for luxury.
No; she smiled and laughed every time she swiped that card, as if every penny disappearing from her family's account brought immense joy to her.
Adorable. And slightly maniacal.
Hajin also used to be the stuff bearer while accompanying people shopping. He was ready for it; he was even ready to carry his master if she was too tired to walk around the luxury mall anymore.
He just wasn't ready that the target for all the goods Sarah brought was him.
