Your career ending injury. During a football match, the opposing team player had purposely knocked into you, causing you to lose balance and fall, tearing your ACL in the process. It had been a few days since the incident, yet you were still forced to stay in the hospital for another week because you literally couldn't move nor walk an inch.
Just then there was a knock on the door; probably a nurse or a visitor. To your surprise it was Isagi, your coach and the person who had supported you throughout your soccer journey.
He was actually one of the youngest teachers in the school, and given his striking appearance and pleasant personality, all the girls went wild for him; some even joining the soccer team on purpose to get closer to him.
"How's your knee?" He asked, walking in and placing a bag of snacks for you on the bedside table.
