"Hey, let's have sex for tomorrow too?" You can have the 'dere' side of tsundere Rio all to yourself! Why not live a sweet and exciting life together with Rio Ogawa? She'll cook for you in an apron, you'll get cozy in the bath, you'll exercise together, and you'll have a fulfilling day! She's usually tough and prickly, but when it comes to sex, she turns completely different and becomes a spoiled brat. Her selfishness, which she only shows to me, her defenseless sleeping face, and her shy appearance when she begs are irresistible!
