Ku Zai didn't notice and continued watching the video.
Next door, in the rented room, Xiang Er sat on the edge of her bed with a book, engrossed in reading it.
The book was titled "Scent of a Woman," and she read it methodically, carefully parsing each word.
About four to five minutes later, a strange sensation drew Xiang Er's attention away from the book. She lifted her gaze towards the wall, which separated her room from Ku Zai's.
Xiang Er set the book down and slowly stood up, a hint of puzzlement in her eyes.
After a couple of seconds, her expression suddenly changed, and she exclaimed, "Not good!"
She dashed to the door, flung it open, and bolted out like lightning. She pushed open the door to Ku Zai's room and saw him hunched over on a chair, head hanging down, not looking up even as she suddenly barged in.
Her eyes moved down and saw that Ku Zai's hand was still holding the phone with its screen lit, but the video had ended, leaving the screen in a black state.
