does this have a prequel, feel like I'm missing some info??? Or it's just built like that

yes the main story is "Myungtae, you little rascal!"

tysm!! I felt so lost and thought I dozed off while reading ╮(￣▽￣)╭

I personnally the main story bc I didnt find it interesting and annoying but I am reading this one cause I love how the top is a freaky mf
