By Chance, I Arrived With the Spring

Educated Heiress x Blind Mortician
To corrupt her widowed sister-in-law, Song Zhimei resorts to every underhanded, disgraceful trick she can think of. But one night, she mistakenly stumbles into her sister-in-law’s secret chambers.
Behind one locked door lies her long-missing elder brother. Behind another stands a gilded cage, filled with nothing but Song Zhimei’s most cherished possessions. And the sister-in-law who has always seemed so frail now blocks her path, iron chains in hand…
In the end, who will be the real prey?
