Shen Yuan hides a genuine giggle behind a sleeve. "Remind me to teach you more slang, in the future," he says, lowering his to reveal his teasing grin. "It sounds so funny coming from Jin-ge. But please, go ahead," he adds, indicating the box with a dainty little wave of his sleeve. "I got them for you, really. Open it, open it!"

The last time he'd ordered food for them both, he'd focused on light, savory sandwiches, not wanting to overwhelm his new friend's palate. But now that the cinnamon rolls have been such a big hit, Shen Yuan feels more confident in experimenting and introducing him to new things. So, the box: inside are four Western-style pastries, crumbly and light, each one with a different flavor of fruit jam filling. Ah, he really hopes Jin Guangyao likes at least one of them!
