What Do the Protagonist's Affairs Have to Do with Me, the Supporting Female Character?

Song Tao’s peaceful, uneventful life of more than a decade was suddenly disrupted by something calling itself a System. It started issuing Song Tao a series of so-called self-rescue missions without even asking. For example: Hurry to the designated location and save the male second lead from being beaten up by a gang of thugs. Song Tao believed it. But when she arrived with a wooden club in hand, she found herself wondering: Why was the male second lead the one beating up the thugs?! As the missions became more and more ridiculous and the information provided by the System increasingly inaccurate, Song Tao had had enough. What did the troubles of the main cast have to do with a minor character like her? Besides, the person the System had picked wasn’t even the male second lead! P.S. The System sends me on one mission a day, and gets the ending wrong every time. Blurb Two: Why is everyone around me saying they like me after I refused to do the missions? The boy next door: Taotao, I’ve liked you ever since the day you climbed over the wall to come see me. My classmate’s older brother: My brother can be a pain, but wouldn’t it be great if you dated me and made him call you sister-in-law? My classmate: I don’t believe you. You say you don’t like me, so why are you always so nice to me? Song Tao had no idea how things had ended up like this. If she could do it all over again, she wouldn’t get involved with any of them!
