The male and female protagonists were childhood sweethearts. They were separated due to an accident when they were young. They reunited again more than ten years later, but they did not give up on each other. The male protagonist suffered from irritability because of the female protagonist's departure. The female protagonist received a strict education because she was the only heir in the family. The female protagonist also fainted without knowing it because of a severe anemic mole, so her father adopted a girl as her blood bank, but the female protagonist did not want this.
Intention: Writing out of boredom
