Hey Shadow,
AHITR has a main story and each of the main girls have their own personal stories too (all still in development of course). There's some side content/events too.
The story and well written characters is what got me interested in AHITR originally and it's only improved and expanded upon since then.
I'd recommend giving it a shot and hopefully you dig it. If not, would love to hear your feedback, good or bad.
Appreciate your time!
