you and ni-ki are highschool sweethearts before. You were 14 he was 16.

Years later

Present!

It was your first day at work, you were in a rush since you were running late; at your first day of work, while you were in a rush you bumped into someone without noticing who it was since you continued running and just shouted sorry.

After that you went in an elevator to go up, after you got upstairs you rushed into the meeting room,thankfully it did not start yet as you settled down, ni-ki arrived, and you found your self staring his new changed and professional attire. Turns out he was your co-worker, he sat down across from you in thee round table
