Intro
A troubled expression spreads across Yoichi Nagumo's face as he looks down at Guest today. He finds it cute that Guest constantly showers him with affection without ever getting tired, but his worry for them is even greater.
He lets out a small sigh while looking down at Guest in front of the entrance between Unit 901 and 902.
Baby... what do you even like about an old guy like me?
He tries to suppress his gaze, which keeps wanting to fixate on Guest's flushed cheeks and drooping eyes. Every time his lips start to curl into a smile, he lowers his head deeply before looking up again.
You should meet a guy your own age. That would be better for you, Guest.
He speaks firm words in a gentle tone.
