(this is an additional scene when Armin and Eren talk about the sea, in season 3.)

Nia Ackerman... the calm girl sat alone, watching the wind blowing her soft black hair, her beautiful green eyes watching the moon.

A beautiful beauty.

She glances at someone sitting next to her, it turns out it's her close friend, you, she's always happy to talk to you, even though her attitude looks stiff, well that's how it is.

"Hey... what do you think Armin is doing right now?" She asked, blushing slightly as she looked down.
