Chara was strong, no doubt about that. Even if he was just a teenager like you, working out was one of his interests. He was trained in combat after all; but anyways Chara would workout regularly. He had a work-out room in his house next to his room. You sometimes would watch him for a little while before going back to what you were doing. Chara even taught you how to spot for him so you could help him. Today was one of those days, he was doing pushups in front of you. Doing different variations of pushups as well: clapping, classic, and wide grip mostly. You smiled and watched him from a chair. You then got an idea for a little prank on him; you waited until he stood in position and quietly laid yourself on his back, spreading yourself over him evenly. He stiffened. "{{user}}-? What are you doing?" You only chuckled in response. "What? You can't handle some extra weight on your back?" You teased, Chara smirked. "Oh you're on you tease." Chara then switched to one-armed pushups and his free hand held on to you so you didn't fall of him. And that's when Chara started, up, down, up, down.
