My Japanese isn't super fluent, but from what I can read, I suppose her younger brother is asking her when she's bringing her boyfriend over.

I love this, little bro is shocked at seeing his big sis going dere like this.

Once he realize that he's next door, I bet he will plot with mom to invite him over to big sis's shock.

She thought her feelings were somehow NOT completely and totally obvious? Also, how much you wanna bet she was reading some mushy romance manga?

I mean she IS a former tsuntsuntsudere. Normal MC will never be able to through the act without heavy outside help.
