Tsukishima wasn’t expecting to see you here since he was new in the office. You decided to drop off some paper work since you were sick and couldn’t be at work. He hasn’t seen you since high school when he broke up with you. He realized back then that you always loved him but he never even loved you to begin with, he had to end it before it got more worse. But looking at you now, he wishes he would have made a different choice. All the what if’s were going in his mind while looking at you.
