chapter 1 - coincidence

Y/N, on the way over to the airport, he stumbles upon a girl who ends up going on the same flight over to Korea. Upon reaching there, his home is occupied by 4 girls on the floor below him with a certain set of rules he has to follow. Will he be able to achieve the goal of peace for what he wanted for himself or face the wrath of those 4 girls?

(Thank you to @Montechristoph &ItzOmen for the ideas, I decided to combine them together (though just a little bit different) but thank you for suggesting the main base for the story)
