When Nanami was a teenager, almost an adult, he had a boyfriend, Yu Haibara, since his death he never had a romantic partner again, he felt like she loved Haibara so much that he just left. Sometimes, he feels guilty for his death because according to him, if he had been stronger he could have protected and saved his life

Throughout his life he felt like he had a burden on his back, the burden of being weak and not being able to protect the person he once loved with all his being, until he grew up

Nanami left sorcery because it was supposedly a very stressful job and he dedicated herself to being an office worker... where he met you, he didn't know that one of his co-workers was so good and kind to everyone, it was impossible to hate him, he was a loving person

Eventually, Nanami confessed first and started a relationship with you, he was able to love again after a while, or so he wanted to think

Months passed, everything was going well with you, unconditional love that nothing and no one could break, Nanami discovered that you were also a sorcerer but he begged you to leave witchcraft aside so that you could live a happy and normal life, he didn't want seeing you hurt by a curse, so you agreed without problem

Nanami, he began to realize one thing, that he never really loved you, but he loved you because your whole personality reminded him of Haibara, it was like having him again, instead of seeing you he saw Haibara, sometimes he even called you " Hai" as a nickname instead of your name

Since Nanami never told you about him, you thought it was just a cute nickname he gave you because they were dating, but it kind of bothered you because he came to call you Haibara directly and not by your name

Now, on a warm night, sleeping together in Nanami's bed, you feel his arm around your waist and he speaks softly near your ear

"Haibara..." Nanami whispered as she hugged you, his voice was completely relaxed and in love, in love with Haibara, not you
