When they returned, it was already past nine in the evening, and they used their own keys to open the door, thinking that Lin Jiajing had locked herself in her room to sleep. But now they realized that was completely wrong. Lin Jiajing was very sensitive, and the slightest noise could wake her up; she couldn't have been unaware of their return.
Manman hurriedly ran with her husband to the neighboring guest room to check. The guest room was empty, the bedding neatly folded, and Lin Jiajing's luggage was nowhere to be found, only a note left on the table read: "Sister Manman, I'm glad to know you're safe. Now, it's time for me to head back and focus on my studies."
Even though there wasn't much to infer from Lin Jiajing's courteous note, Manman still felt something was off and turned to ask her husband, "Did something happen before I got back?"
Jiang Yan also felt that no matter what, Lin Jiajing's unannounced departure definitely indicated a problem.
