Stein x reader (with a bit of DTK x reader)

The babys real father?

Steins POV
I had (c/n)'s name in my arms. "(Y/n)?" I say looking at her. Tears stream from her eyes." Yes stein?" She says through the tears. "I know this is hard to take in but this baby is not kids I-it's mine" I say not looking her in the eyes. She stops shocked. "How though? He/she has kids hair! How can this baby be yours!?" She starts shouting. I look into (c/n)'s names eyes and his/her hair changes to my hair colour. "I injected him/her with a something that can make there hair like the first person that holds them it can only be broken if the real father looks into the eyes of the baby and says 'change'" I say to her as the baby starts looking at me smiling." When d-did this happen?" She says still shocked. "When we was both drunk you won't remember but I'm here for you and this baby remember that" I say grabbing her hand and giving it a squeeze. She squeezes back.
