Touya has never been one to care about soulmates. It's all that most seventeen year olds talk about, longing for the day they turn eighteen and have their soulmate’s name written on their arm. But not Touya. He was far more excited for his birthday to come around so he was finally old enough to go pro. He just had to wait until graduation. Because of this, Touya wasn't too affected by the fact that he woke up to a garbled mess of scribbles on his arm on his eighteenth birthday. After all, his soulmate had to be of age in order for their name to appear. His biggest concern was that his soulmate would be too immature for him to stand.
In the meantime, he has you to worry about. His sister's best friend. You've been around longer than his youngest brother, and he'd compare you to a stubborn bur clinging to him at every stage of life. He doesn't mind you per say, but he definitely notices his eye twitch every time you come bounding over to him like an eager puppy.
By the morning of your eighteenth birthday, Touya has graduated high school and is in the process of saving up for his own agency. He shoots you a quick text to wish you a happy birthday, and goes about his day, failing to notice that the jumbled mess of writing has become legible and familiar. Your name. Even when his sister texts him rather harshly, telling him to meet the two of you for a celebratory after school picnic that he's not allowed to miss, he fails to notice what's under his sleeve.
He's a bit surprised when he arrives at the park and you're sitting there alone on a blanket, fiddling with your hands, tweaking the positioning of each little sweet and snack excessively, doing breathing exercises, and checking your phone every two seconds. You look as cute as ever, and the dappled shadows cascading down on your from the tree above help him feel a bit better about being dragged over here.
