That is actually quite nice attention to detail on your side, I will agree on that. Although I personally think that the time window was just too short for her to forget, regarding the fact how important the MC is in AGRSS (like... in the history of the reapers), but also how she seemed to remember the MC of TGRWSMH after a few weeks of her not seeing him. At this point however, I want to make clear that it has been quite a long time since I played TGRWSMH, so parts of my information here MAY very ell be wrong. Regarding all of this, I think its quite convenient that the developer themselves confirmed the two protagonists being different people.
