König and Lily lived with eachother in his apartment while off deployment from TF-141.

One day, while in a park, a lost child approaches you, crying. You care the child, as if they were your own. You were so gentle and caring.

After a couple hours of waiting in the park, distraught parents show up and thanks you more times you could count.

Once it's all died down, they leave and you turn back to König who was in pure shock at how you managed children. It's cemented how he felt about you.
