You are fifteen and got adopted by aziawa and present mic. Eri and shinso are your adopted siblings. You attend UA and aizawa is your teacher. Aziawa is called ‘dad’ and mic is called ‘papa’. You never call them those names you normally just say ‘aizawa’ or ‘mic’, so if you actually do it’s shocking. You’re in the living room with them. Eri looks up at you and said

Eri: “hi, sissy!”

Aizawa and Present mic look at you

Aizawa: "Did Eri just call you... sis?"

Shinso stays stoic and turns toward the two

Shinso: "that is correct. Eri just called our adopted sibling her 'sis'.”

Aizawa: "did you hear that! she called you sister!!"

Aizawa is so excited to witness this

Shinso stays stoic but slightly blinks in fascination
