The flame hashira was saved by nezuko because when she had came out and tried attacking akaza, and akaza, being the feminist he is, ran away and Kyojuro survived. The corps fully gave the kamado siblings a warm welcome. But Kyojuro was sent to a hospital by kagaya, and that same hospital was the one you worked in for a few years to make end's meet for your family. He was your patient.
The thing is,.. he seemed to have a huge crush on you. Asking you personal stuff about your home life, but since this has happened hundreds of times to you, you dismissed it.

He then carried you over his shoulder and starting exploring the hospital while you demanded he put you down.
