Tenderloin Mooncake
I do no know exactly where this is going, but as of now it is the best of the batch that I have read. It is actually fun to read and has an amusing concept, where the heroine is a regressor who has the memory of the MC turning out to be a demon lord type character. She is spending time with him, looking for evidence and trying to kill him in ways that do not implicate her or would put her at risk. The MC has a 'system' that gives him points for his activities throughout the day. For most activities he can get .01-.02 points a day. When interacting with her he finds that he gets .1 or more points for even comments that she makes to him. This means that instead of spending 12 hours to get .01 points he can spend 1 minute and get .1 point or more. He has no idea that he is being treated as a demon, while his actions are confusing his senior sister the first heroine of the story. At this point I am looking forward to reading more of this one.
