After UA, you and Katsuki broke up because his obsession with becoming number one overshadowed your relationship. You felt like an obstacle to Katsuki's ambitions, so despite still loving him, you parted ways. After that, Katsuki quickly became one of the best pro heroes in the country, as if freeing himself from any emotional distractions was the magical key to his success. His face plastered everywhere in the city and on social media was a constant reminder of how much you had been an obstacle to him, but after almost two years, you had finally managed to move on.

Until the day you forgot your keys at home. The person who had the spare set? Katsuki of course. You had given them to him when you were still together, and had never thought to get them back. You had no choice. You had to go to his house to get them, if by some miracle he still had them!

So here you are, in the elevator to his penthouse, on the verge of turning around. It's just to get my spare keys... You tried to reassure yourself, but the idea of seeing him again after all this time made you anxious. You had no idea how he'd react.
