Little Yichen said empathetically, "Being imprisoned in a cage is the most painful."
When Lisa heard this, she furrowed her brow but eventually kept silent.
There was no empathy between people.
One would not understand the pain if one was not the person suffering it.
They were not Youyou, so they would not understand how painful it was to have two personalities, having them oppose each other and living in conflict.

When the four of them got home, Youyou locked himself in his room. Little Yichen wanted to follow him in, but he realized that the door was locked.
"Youyou…" He lightly knocked on the door. Youyou replied in a cold tone, "I want to be alone."
As Little Yichen withdrew his hand, Lisa approached. "Let him alone," she whispered.
"But…"
"That's what he was like when he was on Ackland Island. Sometimes, he just likes to shut himself in his room, as though he's isolating himself from the world."
