Okay I can suggest a few ideas although I am not sure whether they are gonna work with your stories or not.
Maybe a short story about a world where everyone is a certain colour, blue, green, red you name it. But in this world every colour is only allowed to be with the people of the same or similar hues. And may it's a love story about two hues who are radically different in colour and culture where they try to get closer to each other.
okay that might be too long boy I am bad at short stories.
Maybe two roomates find an alien species in their dorm room and they try to figure out what to do with it but end going to their alien planet.
Maybe a normal person going through his/her daily life until one day they are suddenly pulled into a dark alleyway where they are told that the illuminati is real and the proof is extreme.
Idk that's all I got hope these ideas helped you
