I had an idea for a story based on a TV episode I saw. A male character and female character who are acquaintances were faking a relationship. Is there a story where the same situation started (they can be friends, acquaintances, or even not like each other very much) who fake an entire relationship and end of falling in love? They move in together and have to share a bedroom to fool people who come to their home. They get on each other's nerves. They fake kiss all the time until it eventually becomes real. They even have to fake sex until that becomes real. They have a kid together during the main story.
