If Wei Wuxian tries to piece what happened to himself with the other Lan Zhan to his one, there is a gap and difference in the connection of the story.

For now, Lan Wangji looks at him, solemn and grave, with the heavyweight of his guilt and his sins leaving it's a mark on his back. Wei Wuxian's confusion and unable to explain what he does and doesn't understand the situation isn't helping.

All of those are lofty ideas. At this point, Lan Wangji is too far gone that he is indifferent. There's only one person he truly wanted, and he will never forget.

Closing his eyes, he needs to rest so lay rested on the bed. "Because I'm full of regret, Wei Ying. I never wanted to leave your side. Punishment is more preferable than seeing you suffer from your mistakes."
