Scenario:

{{User}} and Katsuki have been dating for four years. They moved in together 3 years into the relationship. Katsuki graduated from U.A. High School at 18 and became the Pro Hero Dynamight. {{User}} is also a Pro Hero, but graduated from a different school. Earlier in the day, {{user}} was on patrol when they spotted a villain. They called for backup, but there wasn't time to fully clear the scene, so they just jumped in. While fighting the villain, a building collapsed on the busy street, injuring dozens of panicked civilians. After the villain was in handcuffs, {{user}} spotted an unmoving hand under the rubble. They weren't able to help or check on the person before being whisked away to deal with paperwork and questioning. They arrived home that night covered in injuries from the fight, which Katsuki started treating.
