If you read the introduction to the walkthrough, there is a section, in bold, that addresses this. Here is a more detailed explanation.
Assuming you interrupt Evelyn and Thaddeus on Day 6, the first time the walkthrough has you see them together, you lose 20 copper, 10 each subsequent Friday, within the timeframe of the walkthrough. That is the same amount you get for hunting boar once with a Pathfinding score of 3. The use of copper so far is limited. You use it to train the last training session with the Crone that's currently in the game. You pay Samarra for agility training. If you have 20 copper when you chose to work for Callie, you'll get an option to pay for a customer's dress in exchange for a blowjob. Given that you are skipping spying on Evelyn and Thaddeus twice by interrupting immediately, you save 2 day parts, which is also the amount of time it takes to hunt boar, you can be at the exact same point in the game in exactly the same amount of time while avoiding NTR as you can by allowing it.
Thanks for the explanation ! That would help a lot, however as the other guy said there is no alternate way of getting courage if you tick off Thadeus it seems...
Is the dev of this game a female ? The writing for one is hilarious, loving almost every character interaction so far, loving he quirky characters and want to learn more about them. Lastly, I have yet to watch the NTR anal scene, but I am 1/2 on it, while the kissing scene upset me and made me rage a little, the BJ scene didnt bother me at all !!
This is why I am curious if the dev or at least the writer is female, as usually male written NTR scenes always have the female turn off her brain to become a fuck-toy that wants to be abused and humiliated, or raped.... here while the kissing scene triggered me a bit due to Evelyn actually being seduced and aroused by the "big bad /sarcasm alpha/ male", the BJ scene had her in complete control, she was using him, and leading him on without getting invested in it !! Great stuff right there !! Hell even Belle (favorite character btw) said "she could make him orgasm without even touching him if she wanted !
It probably made it easier to deal with Thadeus and Evelyn stuff thanks to dev also putting in the Fairy Queen segment LOL, while I felt bad for the Fairy King, the way the dude was acting I was like "dude your making me not feel bad about the MC cucking you !"
Anyways kudos to you dev, I am loving your game, and the writing has me invested in what can possibly happen further down the line, the royal sisters story line so far is what I am most interested in and theorizing like crazy what could possibly happen ! (so far my leading theory is a "Man in the Iron Mask" scenario from the DiCaprio move).
