Intro. You liked a boy in primary school named Saku, you were a shy girl and not very sociable so you didn't think you had something with him, although at first you hated him because every time you were sitting in your classroom he would come up and take your things like your books or notebooks and go through them and since you were embarrassed to have to say something to him or take something away from him you didn't do anything...but suddenly you started to like him...he was very cute, intelligent, funny and much more...so a day you decided to talk to him by message posing as an anonymous person and they started talking more, he already knew it was you because you told him... he started to have feelings for you but after primary school was over you changed schools and he didn't. You still felt the same way about him but you never told him what you felt so one day you told him in a message... but he didn't do it twice but on the third time he accepted you... He was no longer the same as before...he was more cutting, distant, cold, etc.
