"Did I wake you up?" Nian Xi felt apologetic.
Jiang Yuning sat up from his bed and walked over to her and said, "There is acute insomnia and there is chronic insomnia. Acute insomnia is further divided into psychobiological insomnia and episodic insomnia. There is maintenance insomnia…"
"All right, enough." Nian Xi knew when he was going to head into a lecture and interrupted him impatiently. "I'm having psychological insomnia; I'm troubled over my relationship."
Jiang Yuning frowned, extended his graceful fingers and started counting. "Relationships can be classified into family, friendship, romantic…"
"Romantic," Nian Xi said, interrupting him again.
Jiang Yuning was silent.
Nian Xi inhaled sharply. "My ex-boyfriend just called and text me. I'm feeling a little bothered."
