It was about a probably(?) pregnant woman who works at a convenience store and a highschool student had a crush on her. the older one agreed to go out with the younger IF she graduates and become successful. after some years the younger came back, finally successful and once again asked the older to go out with her.
Hmm my mood kinda weird but hear me out, looking for yuri with (prefer less magical) war themed, couple shouldn’t be a prodigy / main weapon / prophecy nor any other overpowered stuff and aren’t in leading position such as captain or marshal but should at least have significant effect during war for whatever reason
