Shang Beida hugs Casper fiercely. "I'm sorry, baobei. You should never be abandoned or forgotten or friendless or grateful for even negative attention or... you're amazing. I... I know I'm not much, but... you have me as long as I can possibly manage. If I suddenly wake up back on Cang Qiong I'll go cry at Cucumber-bro until he makes his husband use Xin Mo to open a portal so I can get back to you." He'd rather be with Casper than back in PIDW, anyway. And if he ended up in Casper's original world, then fine, he can go bully everyone there into not being shitty to his amazing boyfriend.
