A PROMISE TO KEEP (Mills & Boon comics)

"After the war, I shall return. Let's get married then." Collin, a member of an aristocratic family, and Rose, an innkeeper's daughter, promise to marry each other despite the differences in their social status. However, in the midst of the Napoleonic Wars in a combat zone, Collin receives a letter from Rose one-sidedly breaking off the engagement. Collin returns home unconvinced, but when he goes searching for Rose, he hears that she has gone missing. When he finally locates Rose, he finds her working as a housekeeper for an elderly noblewoman at her manor. But Rose acts as if Collin is a total stranger when he expresses his unwavering love toward her.
