Kuma, the boy, used to be bullied and helped by Tora, the girl. 9 years ago he moved away, and since then he decided he will survive on his own. He grew up strong so nobody look down on him, and he beat people bullying others. As he grew up, so is his sexual desire, but thinking he would never again met the girl he loves, he just let it out on other girls coming to him for sex. Then, after beating his teacher who let bullying happens, he got expelled and move to Tora's school (he now lives in dorm). Both start dating, but Tora is worried because she's the only one feeling good. Kuma has been holding back. So, she bought after-sex pill and asks him to not hold back. Kuma admitted, he hates how he ends up becoming a sadist from protecting himself, and how he loves Tora so much he wants to destroy her. They spent 2 days having sex like animals in her home, then he made her promise to not act reckless like using pills anymore, not until they really become adults.
