SV option to suggest Doraemon manga background that may be forgotten by QM.
Please note chargen 1 only select Doraemon manga backgrounds that happened to Nobita Nobi. As SV can read, there are incompatibilities between Doraemon series that may effect Nobita Nobi differently. After this, there are still next chargen and then crossover choices. SV may suggest crossover option to QM that may or mayn't offered to Nobita in story.
