There is never going to be a confession of the secrets Lan Xichen has kept for so long, of things that were never going to be possible. Now, there is Wei Ying, to remind him.
Lan Xichen pushes himself so hard to like Wei Ying, to pour his own wish for his brother’s happiness into the relationship, that it comes as a surprise when he finds that he genuinely does.
