further than universe

it was from this anime, a girl who lost her mother, her mom was a scientist who went to the south pole and never came back .. ofc she died there but the girl refused and denied that, and she believed that her mom only got lost so she kept texting her every day for over 6 years ( i think).
until she gathered enough money to go to the south pole .. when she got there - where her mom exactly disappeared she found the laptop.. when she opened it the emails kept flooding... it was that moment when the girl finally realized that her mother truly died, and she start crying screaming oka-san .. well ofc the scene and anime r better than how i described it, and it's a hidden gem cuz ppl think its only a childish one ;-;
