Depending on the version you're playing (v0.1.2 is the current I believe) when the hints read, "there are no more *girl's name* events in this version," that's usually the sign that that girl's level has been maxed.
Keep in mind the max levels for each character aren't all the same: some may be as high as 10, while others may be as low as 3 or 5.
I must say this is a really great game. Small issues only include the dialog. Just grammatical errors really, but nothing that completely confuses the dialog to the point I don't understand the conversations. I've sat through actual bad dialog through English subtitled anime(and simple US closed captioning), so the errors in this game is hardly anything. The story is great and the interaction with the guild members and adventurers is fun, playfully erotic, and at many times, extremely hilarious! I'm definitely going to support the developers via patreon, because I want more content!
P.S. what is the deal with the "ghost" at the lake?? I had a very interesting scenario where this thing shows up and nearly drowns me. However, I never saw it again. Looking forward to unlocking that hidden gem!
Delete the file, then reinstall. Try not to download anything else in the process, just let it download completely, and then use the default app installer(if you have a mobile anti-virus app installed it may cause issues as it scans, and possibly flag it) to install it. If the issue persists, reboot your android device and try downloading/installing it again...and remember to delete the old downloads beforehand.
