Hitsugi no Hanayome: Meikon ni Yori, Futari wa Toukarazu Ai wo Shiru

Our married life began the day my husband was resurrected... Aiko, the eldest daughter of the Nijo household, is oppressed by her family. One day, in the midst of her modest life, she suddenly receives a marriage proposal, and wonders if this is perhaps her chance to find happiness. However, this is short-lived when Aiko arrives at the wedding ceremony to see a coffin containing her husband-to-be, Shotaro. Much to her surprise, it had been arranged for Aiko to marry the deceased in a "ghost marriage." Just as she resolves to live her life mourning Shotaro, she hears a voice say, "What is this place...?" When she looks next to her, Shotaro, who is supposed to be dead, is sitting up in his coffin!
