"Based on your description and the tests I just conducted on him..." Wen Shubai frowned and said to Qin Sili, "My initial assessment is that he has a dual personality."
After a pause, Wen Shubai continued, "Let me put it this way, let's assume his primary personality is A, and his secondary personality is B."
Based on the test I just conducted with him, Personality B appeared after he started university, specifically in the third month. After that, Personality A disappeared, and Personality B completely replaced him. This explains why Lu Chiyan's attitude towards you suddenly changed drastically after he went to university; he became a completely different person.
Personality B occupied this body for four years, which was the four years he spent with Duan Linfeng.
But just six months ago, the time you asked me to go to the Qin residence to give him the injection, his A personality returned, and his B personality disappeared. So, you saw a familiar Lu Chiyan, just like he was before he went to university.
So now, the situation is that Personality B has returned, so the Lu Chiyan you knew from Personality A has disappeared again.
To summarize, Lu Chiyan's A personality likes you, while Lu Chiyan's B personality likes that scumbag Duan Linfeng.
Do you understand what I'm saying?
Upon hearing Wen Shubai's explanation, Qin Sili remained silent for a long time, his expression solemn, his eyes lowered, seemingly lost in thought.
After a long pause, Qin Sili asked Wen Shubai, "So, how can we get Lu Chiyan back?"
"Generally, multiple personality disorder is caused by severe trauma. The individual cannot bear such pain, so they create another personality to share the burden. But..." Wen Shubai frowned, somewhat puzzled, "I really can't understand it. Under your protection, Lu Chiyan hasn't suffered any major trauma, so how could he suddenly develop a separate personality?"
Qin Sili said in a deep voice, "Right now, I just want to know if there's any way to bring Lu Chiyan back."
"There are still some ways to intervene and treat it," Wen Shubai sighed slightly, "How about this, I'll go talk to him again."

When Wen Shubai suspected he had a split personality, that he was Lu Chiyan's B personality, Lu Chiyan found it utterly absurd. "Me, a split personality? I think you're the ones with split personalities. Are you all mentally unstable? Seriously, I advise you all to get a brain CT scan. Treat any problems as soon as possible, lest they get worse!"
"Then you still remember what happened in the past six months, right?" Wen Shubai asked [ Lu Chiyan ].
"Of course I..." [ Lu Chiyan ] originally wanted to say "Of course I know," but he suddenly stopped when the words were on the tip of his tongue. Just a moment ago, he tried to recall what had happened in the past six months, but his mind went completely blank.
He doesn't remember; he can't recall it at all.
But Lu Chiyan refused to think of himself as having a split personality, as Wen Shubai had suggested, and tried to explain himself, "It's normal that I lost a small part of my memory because of a car accident and a concussion."
"Your medical report shows nothing wrong," Wen Shubai.
There wasn't even a mild concussion.
[ Lu Chiyan ]: "..."
Qin Sili entered the ward, glanced coldly at [ Lu Chiyan ], and asked Wen Shubai, "Is there a treatment method called electrotherapy?"
