My honest Rating. 1. That 1st singularity arc is one of The FGO mc major character developement inserting the MC there and have him do everything is kinda bad. 2. The saber and shiro pairing is too forced. 3. U said they stayed in fuyuki singularity for 1 mounth, doesnt the HGW last only for 7 says what are u writing. There is a lot of other stuff but these are my main probs with the fic.

いいねShirou and Saber is not forced, you just don't like it and want to sound intersting. Also the MC doing everything makes sense, if he has power he will use it (did you want him to just stay there watching?). And yeah, I thought the war was longer, my bad, but well I can't fix that properly so just take it as not canon...
