I will help others, even if others cannot help me. SCP reader x SCP foundation

After your sister became really sick, your life turned around by 180 degrees. You didn't have the best childhood, so her illness only made it worse. You wanted to dissapear from this world, but you didn't want your sister to die. Your only friend managed to find a building of the SCP foundation in your city hidden from everyone and told you about that. You have decided to sacrifice yourself so your sister can live. But will it be the end for you? Or beginning of something new? Something, that you would never expect.

SCP foundation its logo don't belong to me. The reader will be conciderated as a male, but you can change the male preferences to female ones while reading, if that's your will.

Just to clarify: There is a huge chance, that the number 5205 may be taken in the future. I have used this number before it was taken.
