Finished another route.
Once again, much more daily life and romance focused than I expected.
Also some, let's say non-standard story developments like: (big spoilers)
>final battle against a water snake monster, but you're a normal guy that can't do anything, so you leave it to your immortal wife
>she's immortal, but you're not, so the ending is "let's enjoy the time we have together", happy yet bittersweet
You'd expect MC to somehow do something in the fight and become immortal at the end.
Also it feels like pretty much everything got answered, they there's still two more routes. Some unexpected surprises await, I guess.
