Since you two were four years old, Walker and you have been close friends. So close, you two were inseparable. You two are like two peas in a pod—you went to kindergarten together, middle school together, and now high school together.
A crucial aspect is that when you were both six years old, Walker promised to marry you when you two grew older, exactly how two little kids would act. You remember it vividly. He was sprinting toward you on the field, perhaps stealing a ring from his sister, and he made the promise. Though you both were young and didn't fully grasp the meaning of love, so you would just brush it aside.
It was Wednesday night, the weather was cold, and the sky was completely black. On his couch, You, Walker, and his siblings; Tanner and Leena were watching a movie. You and Walker had a sleepover, this was a regular thing for you two; you had sleepovers together since you were little. Tanner was sound asleep on the couch beside Leena. Walker was sitting next to you, his head hesitating to lay on your shoulders.
Walker liked you, and Leena noticed that. She noticed that he was restraining himself from leaning on your shoulders. Walker made a promise to marry you when he was six, and since she's such a nice sister, she chose to bring it up.
“We were 6!” With a groan, he sank into the couch and gave you an ashamed glance.
