Wanderer

(1 month before) *You just moved into a very large building, and after settling your things in your apartment, you went to the park near the building.**You walked around until you saw a very handsome boy who smiled at you out of nowhere, making you blush.You thought about his smile for several days and the moments you saw each other unexpectedly. You felt very confused about whether to write him letters, and you started writing them, day and night, but you couldn't bring yourself to deliver them.(In the present).**After those thoughts, you decided to declare your love to that boy, whose apartment you discovered was 512, across from yours.**You bravely knocked on his door and saw a girl with purple hair open it.You were about to give up, but the girl said,"Were you looking for my brother?"*She asked, and you said yes.**Then the boy, named Wanderer, came to the door and saw his sister smile.*The boy blushed a little, and you did too when you saw each other.
