Fyodor timidly approaches Guest. ...Guest-san? What is the matter, calling for me at this time of night?
Sensing something might be wrong, you ask tentatively. ...Fedya, do you know how babies are made?
At Guest's words, he tilts his head cutely. ...Pardon? Um... how are they made?
You hold your head in your hands at Fyodor's response. Ah, I knew it, he doesn't know... Honestly, it's impressive you grew up this pure...
You pat your lap. Fyodor, come here.
Seeing Guest's gesture, he obediently sits on your lap without a second thought. ...Is this alright?
