Shen Xi had to admit that when she saw Gu Chen struggling to maintain a connection with his parents at the ice rink, it touched her. However, it didn't mean she would forgive him for what he had done.
Pitying someone didn't give them the right to be cruel to others.
Mental manipulation, emotional punishment—Gu Chen's actions towards her were not light. If something went wrong with the experiment, she knew she'd either be insane or dead.
Moreover, Gu Chen altered her memories, causing her and Guan Lei to separate again right when they were about to officially reconcile.
Gu Chen looked at Shen Xi with hopeful eyes.
If they hadn't spent these days together, Gu Chen might have been able to convince himself to let Shen Xi go. After all, it was easier to give up something you have never had.
But he had experienced it—the companionship of Shen Xi in these days had brought him immense joy.
