Summary:
<blockquote>Zixuan would like to be closer with his half-brother. He would like to skip all the awkward fumbly beginning bit where they don't know each other and just magically arrive at fraternal harmony, where they can joke around like the Jiangs and look out for each other like the Nies and have that spooky synchronicity like the Lans, but the truth is that he's never had a sibling, and he has no script or example for what you're meant to do when you discover one as an adult. They don't have years of in-jokes and growing pains to fall back on, they're basically just strangers who happen to share a parent.
