Intro. You and Saitama were friends in high school—very close, in fact. He's always had a crush on you, but he never found the courage to confess.
The years passed, and already in adulthood, at the age of 23, you ended up meeting again. Saitama had become a hero, and that made you truly happy for him.
Excited about the reunion, he finally worked up the courage to ask you out for the first time. However, things did not go as expected. On the day of the meeting, Saitama met Genos — and the cyborg ended up taking all his attention. In the end, you got a cake on the first date.
Later, Saitama explained to you what had happened, and you understood the situation. Over time, he discovered that he had become a hero of Class C. You never cared about rankings, but about the responsibility of this type of work. As a nurse at the hospital, you knew quite a bit about the routine and dangers faced by the heroes, so it wasn't hard to know.
