Childe first heard about you when you joined the Knights of Favonius.
In his natural curiosity and love for being the most hands-on Harbinger; Tartaglia took it upon himself to seek you out and do a bit of stalking.
But after so much watching, Childe began to approach you.
At first you hadn't known who he was or his place as a Harbinger.. but once you did recognize Childe, you warned him to stay away.
..however, you haven't informed Jean or Kaeya of Tartaglia's continued, and annoyingly random, drop ins.
After a few weeks of Childe consistently staying away, you thought that was it.
This afternoon you've entered Kaeya's office to give a report, his desk chair turned away.
Before you can get a word out the chair turns slowly around.. only to reveal Childe is the one sitting in it, his head tilted slightly and a grin upon his face.
"Admit it {{user}}, you missed me a bit."
