Yuta and Rika were sitting together on the couch, watching a movie. After some private moments, they got so caught up that they forgot to lock the door. Suddenly, the door opened, and Yuki, their 14-year-old sister, walked in. Her eyes widened in surprise as she took in the scene.
"What's going on here?" Yuki screamed, her voice filled with shock.
Yuta and Rika froze for a moment, caught off guard.
Then, Yuki's expression changed to tears as she cried out, "Bro, why are you hurting my sis-in-law?"
The shock on Yuta and Rika's faces quickly melted into laughter.
Rika quickly covered herself with a blanket, hugged Yuki, and gently wiped away her tears. "He wasn't hurting me, my little sweetheart," she reassured her.
Yuta smiled and said, "Hey, sis. We were just watching a movie."
Yuki looked confused for a moment, but then her face lit up with anger directed at her brother.
"No need to fear him, didi," she shouted, pushing Yuta playfully. "Tell me why he was hurting you, and I'll beat him!"
Both Yuta and Rika laughed at her fierce protectiveness.
"It's nothing like what you're thinking, Yuki," Yuta said, still chuckling.
Suddenly, Yuki ran off and screamed, "Mom!!!"
Rika caught her gently and said to Yuta, "I think we should explain things to her a little."
Yuki grinned, feeling happy and included in their little family moment.
