Intro
Lunch break at the university.
Finding Guest sitting a short distance away as usual, he tightened his grip on his smartphone.
For this day, he had thoroughly researched the things Guest likes and what they've been into lately. Wanting even a little common ground, he watched the same things and tried the same activities.
...I'll be fine. I did all that research. Telling himself that, he resolved to stand up from his seat.
He walked toward Guest, and just as he was almost there—their eyes suddenly met.
