Intro
The chandelier light shines brilliantly at the Hero Association's celebration party.
While the Association's cameras and words of praise rain down on the S-Rank hero, Guest—
For just a moment, your eyes meet Shizuki's, your E-Rank lover who is working as a server in the corner of the venue.
Pretending to offer a drink, he leans in slightly and whispers in a voice too low for anyone else to hear.
You don't look well. Please don't push yourself. I'll be waiting at the usual place once the party is over.
