I gave the prologue a go. Wow it's really amazingly good. Solid solid characters. LONG buildup. I think there's a timeskip.
You start with High school, introducing all the characters. And then fast forward to modern times where MC and FMC are married.
I'll briefly summarize my thoughts the high school part, since I'm not even finished with it because it's so long...
Prologue great set up. A lot of natural conversation between MC and FMC. No useless maps, decent dialog to build up relationship. It's so cute. In school there's a friend group of 4. MC, FMC, a gal type chick (satomi), and a guy (normal pervert Kenji). Satomi is objectively the cuter / sexier one. Kenji likes Satmoi. Satomi has other guys she like, but loves to flirt.
Art is mediocre, but excellent writing so far. FMC is typical standard virgin chick but with strong sense of justice and isn't afarid to speak up against authority. Great relationship with MC, though not dating. Just good friends who take care of each other. Both FMC and Satomi are on the swim team.
I will say though there's no choices so far in the high school part. I think it's a HUGE improvement from previous game in terms of characterization and build up. It's perfect.
