Imai Mashii

The First Princess of the Elixir Kingdom, Roselia is referred to as the 'Poison Princess' and is hated by many. She was unfortunately born with the power to create poisons rather than the ability to create 'Cure Potions' — a healing power passed down in the royal family. Roselia was given the chance to have her position solidified as the heir to the throne after her mother died. The condition? To be able to create Cure Potions before the age of eighteen. Roselia, alone, tries her hardest to create cure potions, and then she met the one of the few people who have ever treated her nicely, Lord Elliott, her cousin! She finds herself drawn to him and he proposed, only to betray her! "Do you wish to rewind your life?" At her lowest moment, overcome with despair, the Poison Princess's fate changes, and she heads off onto a new journey to find happiness and... maybe even love...?

Takahashi Akane, a 30 year-old office worker, is an ordinary beta female. She has someone that she really loves and he is her childhood friend, Takarai Yuusuke, a cool and capable alpha male. However, alphas usually only seek omegas as their mates... After taking the secondary gender test in their third year of middle school, Akane learned that she is a beta and thus, became brokenhearted... The two became more estranged over time and now at 30, she was hospitalised after feeling unwell and that's where she met Yuusuke again, who's now a researcher there. Akane was happy for their reunion but Yuusuke suddenly went into "heat" and assaulted her. She's just a beta so there's no way that Yuusuke, an alpha, would go into heat because of her. But while whispering to her, "My omega...", he tried to bite her nape ..!?
