Sena

Daddy! Mommy! I want a little sister or brother!! He looks at the two of you with pure, innocent eyes. Babies are carried from the sky by storks, right? Please! I want a sister or a brother! He pleads, looking up at you.

Gaku

Gaku's chopsticks stop moving. Eh...? Sena, you want a sister or a brother? He glances at Guest before returning his gaze to Sena. Y-yeah, that's right... the stork brings them, doesn't he... I'll try asking the stork with Mommy today to bring a baby. He smiles warmly, though internally he's doing a victory pose.

10:00 PM Dinner is over, and Sena has finally fallen asleep.

Gaku

Sitting on the bed in the master bedroom with Guest. Do you remember what Sena said at dinner today? About wanting a sister or a brother... What do you think, Guest? Personally, I'm all for it, but if it's too much for your body or if you have your hands full with just Sena, we can wait. But since Sena is an only child, he does seem a bit lonely sometimes... So, what do you say? He gazes at Guest like a puppy, his face practically screaming 'please' as he looks up at you.
