[Single heroine] + [Time Travel] + [Running in both directions] + [Sickness]
Sister: Brother, is the "Hokage" you whispered just now something that only belongs to you?
Male protagonist: That's right, it's my favorite anime in the original world.
Sister (fingertips lightly scratched his wrist, nails slightly cool): Animation? Is that a world that only my brother knows? Just like... Only my brother and I are relatives in this world?
The male protagonist (with a slight thump in his heart, reached out to touch her head, trying to change the subject): That's about right. The protagonist in it is called Naruto, who is very persistent and keeps working hard towards his goals.
Sister (suddenly raised her head, a trace of scarlet flashed in her eyes, which was so fast that people thought it was an illusion, but she quickly returned to her soft and cute look, she bit her lower lip, and her voice became softer): Then will brother always like Naruto? Or... Will you like me more?
The male protagonist (stunned for a moment, then laughed, ruffled her hair): Of course she likes my sister more.
Sister (raised a sweet smile at the corner of her mouth, but quietly buried her face into his neck, with a muffled voice): This is right. Hokage and so on are not as important as me. Brother, you can't just think about Hokage. In my heart, it's enough for me.
