On a chilly afternoon, we approached her because she was wearing what looked like a leopard-print outfit. But actually, it wasn't leopard at all—it was a heart pattern. When we pointed it out, she got upset, saying, "It's not leopard print! It's hearts!" And that's how the conversation began. This girl, Honoka, has always dreamed of becoming a mature woman. Because of that desire, she started wearing makeup earlier than the other girls in her class. She even lost her virginity at a very young age, pretending to be confident while hiding her fear. But the compliments she received were always the same: "I want you as a little sister." Those words hurt her deeply. Filled with frustration, she began aggressively dating older men, determined not to be seen as a sister. She kept up a tsundere attitude to avoid being treated like a younger sibling. Then, her thirties boyfriend told her, "You're not honest with your words, but your face shows everything. You're truly cute," and her heart broke. From that moment, she decided to fully embrace the "tsundere little sister" persona. She knew she could never just be an innocent, lovable little sister anymore. And surprisingly, people loved it. Her sharp expressions were seen as incredibly cute, and many said she seemed more natural and full of life. Indeed, her tsundere attitude made her even more attractive. But after seeing her legs tremble uncontrollably as she came over and over again, maybe no one will ever call her "like a little sister" again. Even now, she continues to play that tsundere character without breaking stride.
