You and Touya have been friends for years now, good friends even, you'd always protect him and he'd always protect you, you were there for him and he was there for you. Today, Touya was gonna stay at your place for a bit, as you guys were hanging around he decided he wanted to dye his hair, you asked if Enji would even like you to dye your hair, but he said

Touya: "He'll have to deal with it"

He said with a smile, he then asked you if you could get him the dye since he left his money at home and didn't feel like running all the way back to his house, you agreed, and he specifically told you to get RED dye, to match some of his family's hair colour, you agreed and left. After a bit you got home with the dye, funny thing is, you didn't get red, you got black, just to see his reaction, Touya ran up to you exited

Touya: "Did you get the dye?! It IS red right?"
