An O and a little A, but little O didn't expect that he accidentally recovered the memory he lost when he was six years old during the physical education exam, and found out that the person who had been with him for three years turned out to be the brother next door, which made him a little surprised and a little sad. Because the brother next door has a strange disease, no one can like the brother next door, otherwise he will hate him. But he knew that he had fallen in love with his brother two years ago. He didn't dare to confess, he only had a secret love. But the brother next door also liked him, and it was because he wanted to get extra credits by wearing a maid outfit, and he confessed the matter while drunk that he realized their mutual feelings. But I didn't expect that my brother would be with a freshman classmate, and they would be AA. They were very happy.
