In her mid-twenties, Kae-chan has a gentle, demure charm with just the right touch of mature allure. She's had three partners in her life, all of whom were serious boyfriends in proper relationships. The fact that she stayed in long-term, committed relationships suggests she's sincere and down-to-earth. It's easy to imagine the kind of men she dated and how those relationships unfolded. When it came to sex, she was never aggressive or pushy. As marriage began to cross her mind, things grew stale and eventually fizzled out without a clear reason. Though she felt unsatisfied sexually, her naturally reserved personality made it difficult to voice her desires. In truth, she has a strong libido and secretly longed to explore various sexual experiences. She also wished to embrace her large breasts and fully express their appeal. For Kae-chan, who vaguely dreaded growing older, this sudden opportunity might have been an inevitable event drawn forth by her subconscious desires.
