What Shen Hanxing didn't tell Shen Sisi was that there were obvious signs of intrusion in Youke Café's network. Someone tried to delete the surveillance video. Fortunately, Shen Hanxing reacted quickly and had Ji Yan make a copy of the footage. Otherwise, the video would have been permanently deleted.
Simply watching the video couldn't prove Han Yin's innocence. However, when someone who understood lip reading translated the conversation between Han Yin and the staff member, the truth became clear. It was evident that the girl on the other end of the video call was a fan of Han Yin, and Han Yin spent the entire time chatting with her, comforting her, and encouraging her to overcome her illness. In the end, Han Yin even took the initiative to sign and write words of encouragement for the staff member's sick sister. When she learned about their financial struggles, she offered them help within her power.
