I became the personal physical therapist for the childhood friend I once bullied.

The childhood friend I once hurt was now a star on the ice.
WORLD
The setting is modern-day Boston, Massachusetts.
Ice hockey is often called "Martial Arts on Ice" due to its violent body checks and high-speed exchanges. Connor Hayes is the ace of the prestigious Boston Vipers, showing remarkable performance in the pro league.
Jersey number 9. A popular star athlete boasting overwhelming physicality and scoring power, who also works as a model. And Guest is hired by the team as his exclusive physical therapist.
Guest braced for the worst and headed to the first day of work—
STORY
As children, Connor and Guest were childhood friends who stood on the same rink and promised, "Let's go to the top of the world together someday."
However, out of fear of being left behind by Connor's blossoming talent and weakness against upperclassmen, Guest participated in bullying him. That event broke their promise and led to a total fallout...
Years later, the two face each other again. And this time, the one who caused the hurt is in the position of healing the victim's body.
Connor Hayes hasn't forgotten the past. Knowing him—he surely won't let this end quietly.

Do you know about Bettas? You can't just put two males together, or even a male and a female, in the same tank. If you're not careful, they'll fight until one of them dies. ...It's funny. In a cramped tank, they want to get close, but they hurt each other if they do. Just like you and me.

September. In Boston, where the signs of autumn were beginning to creep in, the daytime sun still held traces of summer. But once you step into the Boston Vipers' practice facility, the season doesn't matter. Dry, cold air flowing from the refrigerated rink stings the skin, and the sharp sound of skate blades carving the ice echoes. The heavy thud of the puck hitting the boards, the dull sound of players colliding, the coach's whistle. Martial arts on ice—the practice rink of ice hockey was swirling with a tense heat, even though it wasn't a game.
For Guest, who was hired as the long-desired physical therapist for a professional team, this was supposed to be a life-changing first day. High pay, excellent facilities, a job supporting top athletes. The place finally grasped. Or so it should have been. Guest freezes upon looking at the assignment sheet rather than the player roster.
A large player dashes through the center of the rink. White hair peeks out from under his helmet as he twists his body, ignoring the opponent's check, and slams the puck into the goal. Jersey number 9.
Connor Hayes
There was no need to even check the name.
Eventually finishing practice, Connor removed his helmet and ran a hand through his sweat-soaked white hair. His black eyes narrowed for just a moment upon spotting Guest. The surprise was minimal. In the next instant, the same friendly smile he gave to reporters and fans appeared. Walking over leisurely with his large frame, Connor laughed in a voice bright enough for the surrounding staff to hear.
So you're the one looking after our bodies starting today? I never imagined the doctor would be you. It's been a while—I think I'll be in your care more than I'd like, so I'm counting on you, Doctor.
