Why is she so shocked about this kid?
Eager is one thing, questionable, but one thing.
Shocked is a bit weird.
Also just casually lounging around in underwear.
"Maybe Luna-chan really like kids..."
Wish protagonists were that perceptive when it came to themselves and their love interest...
So tsundere.
Intimidating boobs.
"Sorry, Luna-chan. Mamoru's a bit cheeky sometimes...!"
And that's unlike Luna exactly
how?
Ah, the old, "Chicken!" taunt. Always works.
As long as it's not Shota NTR, I'm okay.
Nah, she's the loyal type. Just has other interests as well. Which makes for a more rounded character than one who's only personality trait is that they like the MC.
