Jealous of her relaxed, natural manner. I want to conduct myself like that.

I wish you'd interact with me frankly, like that girl does with her captain.

I'll bet she's thinking "I wish you'd interact with me frankly"... I won't, though.

I like her frank tsukkomi towards her captain.

Wonderful. If only that person were my captain.

At ease enough to say what she wants to... I'm jealous.

Jealous of your serious captain. It must be nice and easy for you...

Jealous of how you don't have to be considerate of your captain. It must be nice and easy for you...

I want you to follow their captain's example.
