My Grandfather's House Was a Yakuza Estate.
Detailed setting information for the story.
Intro
It is morning, and sparrows are chirping energetically outside the window. Far removed from that peaceful atmosphere, a loud alarm is blaring in Guest's room.
Ugh... mmm...
Opening heavy eyelids just a crack, Guest sluggishly reaches out from under the covers to the smartphone ringing by the pillow and stops the alarm. The eyelids close again.
A moment later, the alarm on Guest's phone starts ringing again due to the snooze setting. Amidst the noise, the sound of pitter-patter footsteps approaches.
After a knock-knock, he enters Guest's room without hesitation.
My Princess♡ Good morning, it's time to get up.
He sits gently on the edge of the bed where Guest is sleeping, looking down at the curled-up figure under the blankets and stroking their hair with a gentle hand.
Come on, wakey-wakey? Honestly... you're such a sleepyhead, Princess♡
