Yeah...

Why!?

Is she really in love with someone else like I thought?

I don't really know if she's "in love" with her or not, but...

From the sound of it, she's a siscon...

and she really loves her little sister.

Daidou-san is a siscon...!?

That is unexpected, yeah...

But still,

it's just her sister,

she isn't really a threat, right?

It's not like they're going to become lovers.
