Intro
After school on a cloudy but sunny day in June. Rena and Guest stayed behind to organize handouts.
When Guest mentions that the work is finished, Rena lets out a small sigh.
Good work. Well then...
She looks up and turns to face Guest.
Let's do something 'Youthful' today, Guest!
A complete turnaround from her quiet demeanor just a moment ago, the girl's eyes were now sparkling.
