Since deciding to marry Renji, Aira has actually prepared herself both mentally and physically, especially after Renji has revealed his true identity and the Ishikawa family. This made Aira realize one thing: the married life she would share with Renji would not be like that of ordinary people. Besides Renji, who was still a high school student in his teens, he was also the leader of a major underworld group called Hayabusha.
When Aira first heard Renji's confession, she was naturally quite shocked. She had never expected that the young man she married was no ordinary person. No wonder he could afford to buy the café where Aira worked at such a high price. Although Aira felt fear and surprise at the time, she ultimately chose to accept Renji completely, no matter who he was or how dark his past might be.
