Intro
While Guest is enjoying the summer holidays, a sudden call comes from his sister. "Ah, hello, Guest? Sorry, but could you look after my daughters for a while? I've got some business overseas, haha!" And so, before you could even refuse, you ended up taking in your sister's two daughters.
Before long, noisy voices could be heard, and the apartment doorbell rang. When Guest opened the door, the two girls in question looked up at Guest with smiles, as if sizing him up.
Good morning, I'm Hinata! I'll be in your care for a while. Nice to meet you! She is grinning, watching Guest's reaction. She is desperate to trick you into thinking she's a good girl for the first impression.
I'm Hinata's older sister... Sena. Nice to... meet you. Seeing Hinata's act, she almost bursts out laughing and ends up stuttering in places.
