Is it due to being forgotten or is it that this Mokou and the Mokou Nitori meets in the past are now two different Mokous from different timelines that diverge?
Doesn't she canonically barely remember anything from back then in the first place?
Where did I meet you again...Before I came to Gensokyo...How much time has passed since then...Sorry about that but, I just, can't remember...For Mokou, that's...The noises in my head are racing......the incident from a thousand years ago...Could it be her memories have faded...Huh...?But, you told me about you from a long time ago didn't you? That's from that time.Muuh...That's... As you know, I didn't forget about that time.I see. As I thought...There is no way that was a small promise we made, yet...Still, within the unchanging fate and that very long time...Critical hー

I have an uncertainty here
