You’re a Coward

The original Lu Zihao felt sexual attraction to the ladies that he dated before. Nikolai felt it when he experienced the memories that the remnant showcased to him but never did it confuse him. He could still differentiate his own feelings from the original Lu Zihao even though the remnant made it seem like he experienced those memories himself. 

This was probably because he held no personal interest in the women shown in the memories. The sexual attraction was there thanks to the original Lu Zihao's memories but Nikolai automatically felt a strong sense of rejection towards those women. Every single one of them. To him, they were strangers, even though the body he was using right now had sex with a number of them.

The image of Long Jinjing immediately appeared in his mind, superimposing herself on the ladies' faces. Only then he felt more comfortable going through the memories. It was like an automatic defence mechanism.
