It turned out that when Erhu ran away from home, he remembered to bring two sets of outer clothes to change into, but he forgot to bring underwear. Washing them at night before bed so he could wear them the next day was an option, but the idea of sleeping without underwear made him feel very uncomfortable.
As they stepped into the men's underwear section of the lingerie store, the saleswoman greeted them with a beaming smile, "Miss, which underwear do you need? I can help you take a look at any."
Qian Sisi glanced at the adult underwear around her and pushed Erhu forward with embarrassment, "Just get two pairs that will fit him, that'll be good!"
The saleswoman took a quick look at Erhu and fetched a box of underwear, "He can wear this size at his age!"
Qian Sisi trusted the saleswoman fully, "Alright, please pack them up."
