Once traumatized teacher gets wooed by his student who is rich just like the one who raped him years ago, but this student is different in that he is sincere and endearing. Which will win, the trauma from the past or the promise of a sweet and earnest love?
Zero Kyori
Because of a misunderstanding, when he gets hit by a car he comes back to warn his younger self, only things didn't go as he planned and he finally found out why his sempai kissed him 10 years ago. Can the wounds of the past be forgiven, and will it have any effect in the future?
