There's no defined alternate universe for this one, just know that it happens either in high school or college and they still live with their families. There's no context but we can imagine that Yeonjun just got very fed up and hopeless about Soobin's obliviousness (is that a word?)
It'll make you cringe and maybe throw up (my little sister gagged a few times). And, I need a new title so if anyone's got an idea, hit me up !

You’ll see I use the pronoun ‘them’ because in Korean it’s the most used one but it doesn’t mean a single thing here. I just think in Korean when writing sometimes.
