Hana Tsuma to Yoiyama: Botsuraku Reijou wa Junketsu wo Sasagu

A woman from a declining family, Rira Tachibana, is trapped in a harsh home life and denied basic freedoms like being in daylight. Her only escape is through marriage, but her prospects are bleak—her only suitor is an elderly man with peculiar interests. When she discovers a flaw in Azumi, the reclusive heir of the influential Nishioka family, she offers him a proposal. Unaware of the complications ahead, the two enter into a marriage. One is a determined woman from a fallen lineage, the other a withdrawn noble’s son. Their union unfolds as a complex partnership.
