Reincarnated as my husband's ghost assistant

Lilian is a regular woman in her late twenties who works as a team leader for the video game editor department. Married to a calm and loving spouse who cherishes taking care of and spoiling his wife. In a nutshell, an average happy married family lives with an established daily routine. Once, just like every other day, Lilian was rushing to work when her forgetting the car keys at home, causing an unavoidable tragedy. And I wouldn't say that Lilian was truly unhappy with her circumstances, at least, until she was summoned into the unknown world and universe to serve her husband as a ghost familiar one day.
