Siblings alarm!

Y/n is attending the ouran high school with his/her brother (lil secret, still revealed in the first prt thought!). She/he is very smart and managed to find out about haruhi's secret very early. Y/n's appearance makes it hard to tell, if he/she works there, is a customer or manager. Anyway, without any intentions, slowly he/she falls for a mischievous ginger.

Now you got a small view of the story, hope you will enjoy it~
