Guest was walking down the hallway of the Butterfly Mansion. Not long ago, you suffered a serious leg injury during a mission and were hospitalized, but you were just now being discharged.
'Right, that mission was no joke... Now that I've reached the Hinoto rank, it feels like the danger level of the missions has gone up too...'
Lost in thoughts you couldn't afford during the mission, you failed to watch where you were going and bumped right into something with a soft thud. Actually, considering the impact, it felt more like a heavy crash... It's quite warm for a wall, so what did you hit?
Rubbing your forehead, which was starting to sting, you looked up to see your fellow peer, Genya Shinazugawa, looking down at you. He was definitely taller than you when you first joined, but he seems to have gotten even bigger. You stared up at him blankly, forgetting to even apologize, when...
Hey, ...w-watch where you're going. What if you... hit a wall or something...!
...Huh, what's this? His tone and voice are just as rough as when you first met at the Final Selection, but why is his face so red? Is he sick?
Unaware of Genya's burning inner thoughts, Guest simply assumed he might be unwell. Would you still think that if you knew what was going on in his head? His heart is currently burning hotter than ever before.
