Hi! So for the backgrounds (I'm assuming is the player character's role and background), as long as how you resolved it is related to one of them, it'll give you an advantage (an extra 1d6). Whether it helps or hinders you can be determined by the result of the roll and your own story. For example, let's say in this game, the PC is a princess and a mage, and the scenario is an LI enters your room at night, injured, if I "heal the LI using magic", then I get a +1d6 because how I resolved it is related to my PC's role; if I "call my personal guards to kick them out", then I get a +1d6 because how I resolved it is related to my PC's background; if I patch the LI up myself by tearing up a blanket, I don't get any extra dice.
Let's say it is still the same scenario. If you fail a roll, you can see that as your backgrounds have hindered you depending on the kind of story you want.
Using I "heal the LI using magic" as an example. If I've succeeded in this roll, perhaps the PC's magic performs well, healing the LI without issue. If I've failed this roll, perhaps the magic backfired, harming the LI even more; or the type of magic the PC used is outlawed, casting suspicion on myself.
At the same time, you don't have to necessarily make your background a huge deal when resolving the roll. Again, using the same scenario and I "heal the LI using magic" as an example, succeeding in a roll with your Love attribute could just mean the PC being worried and scolding the LI while healing them with magic comes off as endearing to this LI. If the roll is a fail, it could mean the PC's light scolding comes off as rude and inconsiderate, even if the magical healing works without issue. In these two cases, while the PC's role is involved in the rolling, giving the player an advantage, it does not affect the success or failure of that specific scenario narratively.
As for the relationship with Penelope, it doesn't have any mechanics behind it. It's just there to give you some insights as to what the character dynamic is like. You are free to choose any and free to bring it up whenever you like in the story. If you don't like any of the provided ones, you can create your own relationship as well.
As for character sheet, do you mean like a blank document for recording all the characters? I do want to create one if that's what you're referring to, seeing how there's quite a number of characters. I'll see what's the best way to make one.
I hope this answers your question. Please let me know if you need any clarification or I've gotten something wrong regarding your questions!
