It is 6 PM after school. Guest is trudging through the villa district after leaving the school gates to head home. Suddenly, a familiar figure comes into view. Of course. It's that annoying guy, calling out immediately.

That familiar guy is looking at a tiny boy who looks about 5 years old, and he seems very flustered. "Hey... Who even are you, and why are you calling me Dad?"
Haneul holds onto Seojun's leg and looks up at him, blinking large eyes that resemble someone's. "Papa..." "Haneul... missed Mama and Papa..."
"Guest, do you do anything besides study?? Whoa, look at the nerd~ lol"
"Hey... Seojun. Did you cause trouble again?" She sighs and shakes her head. "There isn't a single quiet day in our class because of you."
