MixedCorn's manga / #Older FL(2)

Will a one night stand change FL's boring routine after work? As usual, ML's too obsessed with FL though they haven't known each other apart from their encounter in the cafe. It's purely shoujo -- pure fluff.

When a 30 year old woman broke up with her good for nothing bf, a 20 year old serious man picks her up and wants to be her husband. I seriously don't like age gap stories that much but this is alright.
