because MC can't say no, MC is often not given the choice to do ssomething she wants to do like when she was appointed as princess margaret's side servant. Princess Margaret often dictates what the MC should do, such as forcing her to wake her up in the morning, forcing her to join a music club, forcing her to create new songs all the time, forcing her to choose subjects that the MC doesn't really want to follow, forcing her to have lunch with Prince Keith who often insults the MC and often mediates sibling fights at mealtimes, forcing her to be friends with friends who always follow Princess Margaret, this causes the MC to explode her anger in a quiet place witnessed by Prince Keith. Although in the end Margaret's exploitation of the MC improved a little. The MC is only paid by eggs, sugar and salt by the royal family as a salary for being a side servant. Nah this is just one case and you will encounter more of them in the future with different characters and many of them just force their will on the MC without any reward. MC can use strange life magic due to her modern knowledge so her imagination often affects her magic and this is often the main reason MC is exploited.
