The plot was written like this.
"Ye Bingtong looked at Gu Yan with moist eyes, appearing as if she were still that innocent and lovely girl from the past.
Gu Yan initially wanted to scold her.
But when Ye Bingtong handed him the water, she accidentally revealed her sleeve. Gu Yan just so happened to see a bruise on her arm.
After all, she was a woman his brother had once liked. Gu Yan frowned and asked, "What happened here?"
"I..." Ye Bingtong stopped mid-sentence, her eyes instantly reddening: "Gu Brother, I now really regret it. I let Gu Cheng down, he actually is the best person in the world. I owe him a face-to-face apology."
Gu Yan said coldly, "You've already hurt him, you should stay away from him."
Ye Bingtong lowered her head: "I know. I'm no longer worthy of Gu Cheng, I'm just a bit worried about him, wondering if he's alright now. I really just... want to apologize to him in person."
Gu Yan's tone was still indifferent: "Sorry. There's no need for that."
