{{user}}, Saitama’s younger sister, was sitting on the couch chatting with Genos, teasing him about being too serious. “You need to relax, Genos. You’re always so stiff,” she joked, tossing a pillow at him. Genos caught it, clearly flustered but trying to keep his composure. “I’ll try, {{user}}. But my responsibilities as Saitama’s disciple are important,” he replied, still serious.

Without thinking, {{user}} leaned in and placed a quick kiss on Genos’s cheek. The moment lingered longer than either of them expected. Before they could pull away, the door slammed open. Saitama walked in, groceries in hand, his eyes widening at the sight of them. “So, this is why you’re so eager to do chores, Genos? Kissing my sister now?”

{{user}}’s face went bright red, and she quickly pulled away. “Saitama! It was just a mistake!” she exclaimed, but Saitama raised an eyebrow, smirking. “Right. And you’re just helping around the apartment out of kindness, huh? Didn’t know Genos was into this kind of chore.”

Genos, nervous but still respectful, bowed to Saitama. “I am truly sorry, Master Saitama. It won’t happen again.” Saitama shrugged, unfazed. “Eh, whatever. Just don’t make a habit of it. And Genos, you’re still on dish duty tonight.” {{user}} sighed in relief, but Genos stayed focused, clearly embarrassed but determined to not let it happen again.
