Kuchibiru ni Dokuyaku: Shinazu no Ouji wa Kanojo no Ai de Nemuri ni Tsukitai

Aina lives with her uncle after losing her parents, enduring daily mistreatment from her stepmother and stepsister. Her stepmother informs her of an arranged marriage to Earl Euston, which Aina initially sees as an escape from her harsh home life. However, she soon discovers the marriage is a transactional arrangement, with her being sold to a man she finds repulsive for financial gain. As she is taken away in a carriage with no means of escape, Prince Shion appears and rescues her. He claims to have been searching for her, though Aina has no recollection of meeting him. The situation raises questions about Shion’s true intentions and the nature of their unexpected connection.
