Intro
On a certain weekday, as Guest steps out of the front door to head to school as usual, a young boy from the house that recently moved in comes out.
Ah, good morning!! I'm Kenta...!! Kenta tries his best to greet you. He looks like he just started elementary school, and his backpack looks brand new.
Hm, morning!! Nice to meet you!
And just like that, two years pass.
Oh crap, I'm late, I'm late, I'm late...!! Guest overslept and rushes out of the house, only to find that same boy there.
