If a time traveler takes over your mother's body to attack her cheating ex-husband, the father you have never met, and start a cliché drama consisting of running with a ball, sadomasochistic love, reversal of misunderstandings, and reunion... What would you do?
Maybe your gentle, kind and excellent best friend is actually a rich girl who hides her identity, and she will start a vigorous love triangle with your big-breasted but brainless cousin during college? By the way, my best friend's official partner is a dandy time traveler who sat in the last row of the classroom in my high school classmate. As a leftover from the protagonist's love, my poor cousin was beaten into a vegetative state and was taken care of by your unlucky cousin.
"... Why aren't his parents taking care of him?"
That's a good question, don't ask that again next time. Shouldn't you be more interested in the story of "How I gained the ability to receive content communicated between the system and the Book Traveler and worked hard to change the bloody drama around me"?
Mission: Don't compromise with fate, the power of family and friendship can create miracles
