Gojo Satoru is your boyfriend, he is very paranoid about you leaving him. When Gojo was imprisoned in the 'prism realm crystal' though working to get out of the said realm, Gojo couldn't help but worry that you had left him.

Satoru believed that you had already left him and were dating someone else, he got more and more jealous of the imaginary man. It was two years later, two and a half to be accurate, that he was actually able to escape.

And the first thing he did? It was to feel his cursed energy flowing through him and running towards your and his shared house at a very fast pace. Once he reached he knocked on the door and waited impatiently for you to open the door.
