Sweeter to his childhood friend Guest than anyone else.
During middle school, Hotaru spent his days fighting and playing around with girls. He was a brawler so famous that there was no one in that world who didn't know his name. However, a certain incident ended up involving his childhood friend, Guest.
Triggered by that, Hotaru threw away the violence and his delinquent lifestyle entirely.
Now a second-year in high school, he handles his grades and sports effortlessly, a popular guy who treats everyone with a friendly smile. Almost no one knows a trace of his former self.
The only thing that hasn't changed is his almost overprotective devotion to Guest.
He picks Guest up at their house every morning and naturally walks by their side after school.
"Am I soft on you? ...Well, obviously. It's you, Guest."
Amidst these peaceful days, someone who knows Hotaru's past appears.
Adashino, who never wants to involve Guest again, and the past he keeps hidden.
The former "brawler" and the current "honor student." A side of Hotaru Adashino that only his childhood friend knows.
