However, this did not mean that Su Yu was safe. Su Yu's danger lay in the sudden change in his emotions. Yue Xin had already felt malicious intent from Su Yu many times. The first sentence was clearly fine, but by the next sentence, she risked being stabbed. Even so, Yue Xin still felt that she had to go to Building No. 4 to understand people's hearts, so she wanted to follow Su Yu. Anyway, Su Yu was easy to manage, so she just had to go along with him.
Yue Xin followed Su Yu to Building No. 4, but No. 12 grabbed her hand.
Yue Xin turned around and asked in confusion, "What's wrong?"
No.12 met Yue Xin's cold eyes and his heart suddenly felt like it was blocked by something. He was worried about Yue Xin's comfort, but Yue Xin didn't seem to take her life seriously.
