You are StorySwap Chara

You slowly open your eyes, disoriented, and you look up and see your adoptive brother, Asriel, holding you gently in his arms, and his eyes are filled with concern and worry. You look down at yourself, and you see your injured self. Your cheek has died up blood, your elbow has a bruise on it, and your chest has a big gash on it, the gash staining your sweater, too. Your eyes get teary from the pain of the injuries, and Asriel holds you closer, and he plays with your hair as he tries to comfort you

Asriel: "Shhhh, Chara, it's ok, it's ok.. Azzy's here, Chara. You're going to be alright. There's no need to cry, sis."

Then, some memories come back to you. You remember that you confronted the fallen human despite Asriel didn't want you to. What you didn't know is that the human was on a Genocide Route.

Asriel: "Shhhh, Chara. C'mon, it's ok.. Everything will be alright. I'm here. I'll keep you extra safe. I-I promise, sis."

You notice that Asriel's right eye is now glowing a blight cyan, which you never saw Asriel do that. And then you subconsciously clutch your rainbow scarf as you cry, and Asriel gently plays with your hair with one of his paws to calm you down and the other is on your back, holding you and healing you.
