And he is very happy to assist! 

"I feel like this has to count as a meal." 

"Meals are at appropriate mealtimes," she says, "and it's halfway through the afternoon."

"Ah, but you haven't eaten anything else today, so it's still technically breakfast." 

"That's not how it works," she says, eyeing the remaining buns with undisguised lust. 

"No, I'm pretty sure it is," he says, feeding her another piece of the red bean bun.

Then he will have someone kneeling before him moaning in lust around his fingers.

You know. Medically. 

Well, you can tell it's medical by the fact he is doing it in public with no shame. 

Experience has taught him that she probably isn't going to bite his fingers off, but seeing how enthusiastic she is--

She is very lucky that he is noble enough that he will risk his fingers for maidens in distress.

"You know, a few buns isn't a proper meal. I could take you somewhere for one,  before I take you back to your house."

"...does it taste this good?"

"It tastes even better."

Involuntary noise. 

"...I am being tempted by demons," she says, in the tone of voice of someone being tempted successfully.

"I solemnly swear no demons will be involved in any of the food preparations."

"It is a very bad sin to eat food offered to idols," Mariam says. She tries to stand up and collapses to the ground.

He will simply help her up in a gentlemanly manner. (Goodness, she is skin and bones. He simply has to get her to eat more food. ...for compassionate and medical reasons.)

She leans on him as she walks. She feels a shiver pass through her when he touches her; it feels like her skin is buzzing. 

He calls for a carriage and helps her up into it. 

If she's a sucker for sweet things, he knows just the place and... it isn't technically in the pleasure district. Just close to it. 

Mariam completely misses his courtesy here, because she doesn't understand the geography of Chang'an and is also fully intending to prostitute herself for red bean paste. 

"What's your name?"

"I'm Jing Yi. And you are--?"

"Haddad Mariam."

"It's a pleasure to make your acquaintance, even if we are doing it in the wrong order."

"I've never ridden in a carriage before."

"So that's, what, three new things you have done today?"

"Being touched by a man I'm not related to, riding in a carriage, seeing a doctor, eating buns..."

He's not sure which of that list to be most baffled and concerned by. "You haven't been touched by a man not in your family?"

"...yes...?"

"No one ever... held your hand? Even when you were a little kid?"
