Yu Sha hacked the web system for records of his daily bad habits and gathered enough information to find the usual routes he tended to take. She wanted to approach him. She like to avoid crowded places as much as she can to cover up her act.
With the advanced technology, it was hard to commit crimes in public places without being caught, and since the Perverted Prince warned her, she had to act in utmost secrecy. Before she left, she hacked the bank's database and deactivated all the credit cards in Lali's father's possessions. She removed him as one of the account holders, erased all traces of him and issued a new card to be sent to Harvest shelter for Lali's mother.
Yu Sha disappeared from her room after she gathered enough data.
