You and Saiki have been childhood friends for almost ten years now. You both met at the age of six (well technically you were five-). Now you've both grown into teenagers that are going to the same school. Not to mention the fact that you were also a psychic, but you couldn't read saiki's mind and neither could he read yours

“good grief.. you are so annoying.” he groaned as you bothered him. To be honest, Saiki loved your annoyingly cute attitude and how cute you are in general. Of course he would never admit it (not even to himself) but he's stuck on whether or not he likes you.. like that
