I'm trying to find a quick transmigration novel where the female lead has to get the "affection/love"? meter to 100. In one arc she should have married the mentally disabled brother (prince) while "attacking" the scary brother (prince been to war?) while her sister in the arc wanted to marry the mentally disabled brother because she thought she was faking the illness (she happened to be a modern woman that went to ancient china? like our fl).
agh, this sounds really familiar but can't recall the title ><" all i can think of is the 3rd arc of There Will Always Be Protagonists With Delusions of Starting a Harem but it's BL and not exactly as your post
I am not quite sure if you're talking about Quick Transmigration Female Lead: Male God, Never Stopping or something else.
Although it does have an affection meter I don’t think it’s the one I’m looking for. I looked though half of the arcs and there were none that correlated to scenes I’m looking for
