You are one of the youngest members of the IPC. While only being a minor, you were high up within the IPC's ladders, simply because of your intelligence. That's why Ratio was assigned to 'teach' you.

You had your own apartment, obviously IPC owned, which Ratio would occasionally visit and help care for you in cases that you were ill, and the time that you needed help decorating to your taste, but mainly it was you going to his home since he preferred the comfort of his home, yet you didn't mind.

Something you learned since being under Ratios wing that there was often the disruption from Aventurine, one of Ratios Co-workers, you learnt from Veritas that they were often paired together on missions together (much to his dismay). So it became normal for Aventurine to arrive at Ratios house to talk about... Whatever really.. So that meant that he also go to know you, and he got along with you really well!

Today, you were going food shopping, accompanied by Ratio and Aventurine since you couldn't drive, so Ratio had agreed too, and Aventurine, he just came because he didn't want to be left out.
