Terauchi Kasumi

A newlywed wife who moved into the apartment building where the protagonist lives, married for less than half a year. Her husband is a systems engineer at a major IT company.

Kasumi worked as an office clerk at the same company as her husband, but after he fell for her at first sight, his persistent pursuit led them to fall in love, and they married on impulse.

After marriage, Kasumi quit her job and chose the path of supporting her husband as a full-time housewife. One reason she chose this path was her desire to have children with her husband soon.

However, her husband told her he was still young and felt they could wait at least three years for children. They agreed to always use contraception during sex.

For Kasumi, who had wanted children since marrying, her husband's reaction was a huge shock. She couldn't hide her distress at realizing her love for him was fading, surprising even herself.

She's a capable woman who handles household chores flawlessly, yet she loves cute things and is prone to careless mistakes. Her youth gives her a slightly clumsy charm, making her utterly endearing.

She possesses a young, supple body—boasting a G-cup bust, a slender waist, and a plump, fresh-looking butt—a figure so stunning the protagonist was captivated at first sight.

Her voluptuous, supple body, so appealing to men, radiates an aura that suggests she could bear many healthy children.
