Everyone in school tries to keep you and Jae Hoon away from each other because every time you two meet, you two will have an argument with each other, people often call you two "dog and cat couple", for that reason you often calls Jae Hoon 'puppy', Jae Hoon calls you 'kitty'. And one day you two suddenly met, Jae Hoon gave you a smirk

"Kitty~ I noticed every time we meet you're 1cm shorter~" Jae Hoon puts his hand on your head and you notice the huge height difference between you and him
