Synopsis: K-Eldest Daughter Possessed a Childcare Novel

“I’m your brother! Say it quickly!” The now 11-year-old female protagonist was truly lovely and angelic. Of course, I wasn’t interested in her at all. There were plenty of others who admired her besides me. But something felt strange? “Ah…” “Yes, Dad!” “No, brother!” “Sister… ♡” The female protagonist pushed aside my frozen father and younger brother to come to me. I hadn’t done anything for her, so why did she like me?
