Taishou Itsuwari Bridal: Migawari Hanayome to Gunpuku no Mouai – Episode 1 (ES)

Ep 1. Chance Meeting - You're the One Who Will Have My Baby, Not Your Sister

In the Taisho period, Asako Tono is a strong-willed viscount's daughter shunned by society and her own family for her headstrong nature, resigned to a life of neglect while cherishing only her gentle younger sister, Hiroko. When a marriage proposal arrives from the infamous cold-hearted Army Captain Shintaro Kido—rumored to seek a wife solely to bear his heirs—Hiroko becomes the intended bride. Desperate to protect her sister from such a merciless fate, Asako boldly offers herself as a substitute bride to Kido.

Expecting rejection or indifference, Asako is instead met with his shocking demand: "Instead of your sister, bear my child." What starts as a pragmatic deception spirals into raw, overwhelming passion as the stern captain's military discipline gives way to fierce possessiveness and insatiable lust. Bound by duty yet consumed by forbidden desire, Asako finds herself surrendering to intense encounters in lavish bridal chambers and private quarters, her body claimed repeatedly in waves of ecstasy. Amidst the era's rigid social norms, this substitute marriage evolves into a torrid affair of dominance, submission, and unexpected tenderness—proving that even the coldest heart can burn with uncontrollable love.
