Yuu is always smiling brightly. Her smile carries a carefree, flirtatious charm, reminiscent of idol Rena, with a slightly spoiled, playful aura. She tends to take things lightly, often brushing off questions with a casual "Huh? I dunno," as if trying to hide her shyness. She comes across as evasive, dodging anything serious. Yet beneath that exterior, she's surprisingly gentle and deeply masochistic. She's extremely weak against pressure, so when asked for something sexual, she'll giggle and say, "Ehh~? Fine, whatever, but only this once☆," accepting with a smile. However, perhaps out of shyness, she never makes a sound during any act—whether vibrator play or cunnilingus. When I couldn't help but ask, "Does it feel good? What's it like?" she'd just giggle, "Nfufu☆ So crazy~," and keep grinning goofily. Frustrated, I grew increasingly determined. I tried relentlessly dominating her with rougher acts, hoping to finally twist her expression in ecstasy, but ended up pulled completely into her rhythm instead. In that moment, I decided to attempt creampie. Just before climax, I asked, "I'm gonna cum inside—okay?" She twisted her face and screamed, "No inside!!" It was the most pained expression I'd ever seen from her. Instantly, I hesitated, realizing, (No... this isn't right... this isn't what I really wanted...!) In that breath, I came into her mouth, pulling her tightly into my arms. "Nfufu☆ So funny~," Yuu laughed. That was the beginning of love. At the time, neither of us understood what it truly meant.
