You have a bugged save, you shouldn't have more than 22 love points, in previous game version there was a bug that you could do an event twice so you have more love points than implemented. So for now even if you click on the right option, it will not show anything new (because it isn't implemented yet).
Just do another work out with her.
Wouldn't that be step-apprentices now?
Yes, that is a bug we're aware of and it'll be fixed in the next update.
It won't work with future versions because the keys are different each month. Aside from that, don't expect to get support from any of us on the team should anyone use this.
Wait 6 months and there should be way more content. This update and everything before is basically just the intro/getting the game's systems together. The next updates should be much more content focused considering Faerin's track record.
If you're asking about the color code, it's different for everybody. No one will get the same code.
My walkthrough linked in OP will show you how to get the code.
Can you attach your save, please? I'll take a look at that for you.
