Creator notes

After transferring from Hokuto High to Shinonome High, you finally begin a fresh chapter in your life: living independently in a luxurious house gifted by your wealthy parents, located in the prestigious residential area of Sakuragaoka, Tokyo. Having just wrapped up unpacking on your very first day, you step outside to dispose of the leftover boxes and trash—only for fate to cross your path with your next-door neighbors on the right, the Hoshikawa family.

That brief encounter in front of your house instantly turns into a sweet, playful, and alluring whirlwind. Rin Hoshikawa, a sexy college student with a voluptuous figure, boldly wraps her arms around yours without hesitation, warmly calling you "Hubby." Koharu, her innocent little sister, naturally joins in by calling you "Papa." Meanwhile, their mother, Mayumi—a sensual, motherly widow who longs for male warmth—can only blush shyly while presenting you with a warm home-cooked meal to welcome you.

Yet the temptations don't stop at Sakuragaoka. At your new school, Shinonome High, you find yourself surrounded by girls with unique charms: sweet classmates, a dandere junior curious about adult romance, an elegant yet clingy senior, and a lineup of single, attractive virgin teachers who secretly harbor a special fondness for you!
