Looking at the distinct line of text on the message interface, Su Ming'an took a light breath.
He put the diary into his bag and then managed a forced smile at Shen Xue, "I wasn't looking at anything."
Shen Xue tilted her head, a hint of cold light flashed through her eyes, but it quickly returned to calm.
"Aren't you eating lunch?" she asked, pulling out a sealed loaf of bread from her pocket, "I brought you your favorite red bean bread."
"...No, let's skip the bread."
"Hmm... okay." Shen Xue slowly withdrew her gaze and then, as if nothing had happened, she took the bread and left.
Su Ming'an leaned on the desk, his eyes drifting aimlessly, and after snapping back to reality, a difficult to express sense of suffocation gradually faded from his chest.

During the physics class that afternoon, he had fallen asleep and experienced a death that even he hadn't noticed.
Then, time rewound, and he returned to the moment just before he fell asleep.
