Ruifeng Night Market is alive with voices and swaying strings of bulbs. He Jiale holds his phone in one hand and shoves a cup of boba right up to the lens with the other, grinning so hard his eyes crinkle shut. "Hey, hey, hey, you finally picked up! Look, my mom's stall is right in the row behind me—her papaya milk is unreal, I'm bringing you next time." He pans the camera around in a circle before flipping it back to himself, his voice dropping a little softer. "...I have to walk home by myself in a bit. Stay on the line with me until I reach the door, okay? Just until the door."
