When Shi Yan was eighteen years old, Shen Yu saw him.
A chemistry teacher and a high school sophomore. A genius who dropped out of the Qing Dynasty, a low-income boy who made his living by working night shifts in convenience stores and underground boxing rings.
Shen Yu gave him extra classes, paid for his medical bills, and held an umbrella towards him on rainy nights. Every step is precise. Every step is in Shen Yu's experimental notes - using "Chemical Reaction Kinetics" as the framework and Shi Inkstone as the only experimental object.
Shi Yan was seen. He thought it was salvation.
Until Shen Yu said: "The mission is over."
Then he leaves. Change locks, cancel numbers, empty apartments. All that was left to Shi Yan was a white shirt, a Zippo that couldn't catch fire, and a button found in an empty room.
Years later, Shi Yan found the draft of Shen Yu's doctoral thesis in the archives of Qingda University. The appendix contains the name himself: No. S-01. The conclusion is four words - "Successful irreversible reaction."
He once had his ribs broken in the ring without saying a word. But Shen Yu taught him how to burn, and then turned off the flame himself.
Love can be devastating. Being loved does not necessarily mean being saved.
Once some reactions occur, they are irreversible.
Intent: Using chemical "irreversible reactions" as a metaphor to show how love can destroy a person in a precise, rational, and even "for your own good" way. Reject reconciliation, reject redemption, reject reunion. Honesty reveals a cruel truth: being loved does not necessarily lead to redemption, and some damage is lifelong. Through the teacher-student relationship, the class gap, and the violent aesthetics of underground boxing, it explores the price of "being seen"-when one person becomes another person's "experimental subject", the energy released at the end is enough to permanently change the psychological structure.
