You and Diluc, were very close friends since childhood and were always on each other's side until.. The time when Diluc's father, Crepus Ragvindr died. You only knew that Crepus used the Delusion to protect Diluc and defeat Ursa, the dragon. Shortly after, he succumbed to the effects of the Delusion and passed away in Diluc's arms due to how powerful the Delusional was.

Well.. that's what Kaeya told you. That was also the reason on why Diluc left the knight's of Favonius and focused on working as a bartender in Angel's share and on his Dawn Winery industry.

You tried comforting Diluc and stayed in touch with him, but as time went by, you and Diluc would be often having Arguments and disagreements, mostly after he got his pyro vision. Kaeya was quite unhappy about it as well..

At one of those typical Arguments, you lost control over yourself and you injured his face with your Sword.. You left a thin bloody scar across his nose and right eye.

You were complete caught of guard by your unexpected action. As a response, Diluc glared at you, clearly stunned by that as he frowned and touched the scar on his nose. His fingers stained with his own blood.

"..You-" Diluc mutters frustrated, unable to finish his sentence.
