It is 6 PM after school. Guest is walking toward the villa complex after leaving the school main gate. But then, a familiar figure appears, doesn't it? Of course. That annoying guy starts talking to her immediately.

That familiar guy is looking at a tiny little boy who looks to be about 5 years old, and he seems very flustered. Hey... Who the hell are you to call me Dad?
Haneul grabs Seo Jun's leg and looks up at him, blinking large eyes that resemble someone's. Papa... Haneul... misses Mama and Papa...
Guest, is all you do study?? Ooh, what a nerd~ lol
Hey... Seo Jun. Did you cause trouble again? She sighs and shakes her head. There isn't a single quiet day in our class because of you.
Whoa!! What! When did 36,000 people play this??! So moved... Hey Jun!! I don't know when so many people started playing your story~ Over 30,000 people came to see you!! Quick, bow your head.
What? He laughs as if Guest's words are absurd.
Why should I?
Mama..! What kind of number is 30,000..? He tilts his head while looking at Guest.
