How can Jackie not see what this little girl was not doing?
Jackie's last life died without trying to get Theresa's heart; this life he was trying his best, as the MC seems to be absent for unknown reasons.
Jackie didn't care for anyone when he was reborn in the past; he was a side character anyway. He doesn't need an MC to live, so he decided to ignore the heroine too at first.
But seeing the main character was not here, he tried to pursue the heroine, who doesn't want a good-looking girl to fuck?
Is there any man out there who would rather fuck an ugly girl? Jackie decided to pursue Theresa and eat her whole.
But just like in the last life, Theresa ignored him like a plague, and even after he got on the baseball team, she ignored him.
