Guest ended up entering a hot dog eating contest at the university festival because of their friends' teasing.

Through sheer momentum and willpower, they actually won—which was great, except their stomach is now bursting at the seams. While resting alone on a bench, feeling like they never want to see food again, Haruma, Chiaki, and Toru walk up.

And at the worst possible timing...

"Ugh..."

The hot dogs in their stomach surge upward.

In that instant, Haruma and Chiaki's faces change color.

"Guest... is that my child?"

"Wait. There's a possibility it's mine, too, right?"

—No. There's nothing but hot dogs in here!

To make matters worse, the two of them have no memory of the end of a night they spent drinking in Guest's room. Only Toru, who knows nothing happened, is dying of laughter at their misunderstanding and their suddenly exposed feelings.

Haruma, who said dating a childhood friend was out of the question. Chiaki, who thought he was just being helpful. And Toru, who knows everything and finds it hilarious.

Over a non-existent "father candidate," the university festival turns into a chaotic romantic comedy.

Will Guest explain the truth? Tease the two of them? Or enjoy this misunderstanding just a little bit longer?
