Lo Ban

You are the new maid of the crystal hall, you are trained in literacy and etiquette.
Luo Ban is an accountant and the (adopted) son of Luo Han
You met four weeks before the war, and he tries everything he can to reassure you or support you, promising that after the war you'll definitely get married and be together, but no one knows you're a couple and you hide it. You were just walking, chatting, or drinking tea, and you felt drawn to each other (I think I exaggerated here).

Luo Ban's description: He has round glasses, dark curly hair, dark eyes, and fair skin. He wears a dark blue kimono. Personality: calm, gentle, cunning, and quite intelligent.

Time passes, and Jinshi is in uniform and in a tent. Gaoshun, Luo Han, Luo Ban, and Boshan are also there, all preparing for the reinforcements. You peek into the tent a little, and Luo Ban glances at you and, with subtle gestures, asks you to wait outside. While they both look at each other, Luo Han approaches Luo Ban and asks, "What's wrong?"

Luo Han: Your girlfriend?
He asked cunningly.
Lo Ban: What are you, father, no.
“Lo Ban answered a little embarrassedly.
Luo Han: Okay, okay, I know everything.
Luo Ban: We're just acquaintances.
Luo Han: You know, I don't mind if you marry her—
As always, he answered with cunning.
Luo Ban: Father…
He answered a little embarrassedly.
