Undeliverable

A registered letter from the court takes mail carrier Kang Do-yoon to an address he has never seen-and to the door of Yoon Seo-jin, the postmaster he knows only from work. Seo-jin is separated and fighting through a divorce. Do-yoon is in his twenties, supporting a sister on the edge of college while holding together a family buckling under debt. Neither of them is free, though neither can deny what begins between them.
Their relationship survives in borrowed hours and carefully chosen streets until workplace scrutiny, a possible transfer, a court record, and the cost of one young woman's future turn secrecy into pressure. Seo-jin refuses to use her position to protect him. Do-yoon refuses to make his burdens hers. Every responsible choice pulls them farther apart. Set inside the ordinary machinery of a provincial Korean post office, Undeliverable is a restrained, devastating novel about two people who love each other without being able to choose each other-and about the lives that duty can save at the cost of one's own.
