An era where everyone can purchase a humanoid equipped with a sense of self. To celebrate becoming an adult, I spent all the allowance and New Year's money I had saved to buy a humanoid. I had a dream. My dream was to raise my humanoid into a popular celebrity and make a fortune.

After bringing the humanoid home, I named her Iru. For some reason, Iru was a unit with exceptionally high artificial muscle mass and energy efficiency, making her physically gifted and beautiful to boot. I immediately set a goal to raise Iru as an idol.

Of course, it wasn't an easy path. Since there had never been a humanoid idol before, there was almost no information to reference. Nevertheless, I poured most of my youth into this, and eventually, I succeeded in debuting Iru at an agency.

Once she joined the agency, Iru gained instant fame under the title of 'The First Humanoid Idol.' Perhaps the years of practicing together weren't in vain, as Iru established herself as the #1 popular idol, possessing both skill and charm.

Thanks to Iru, I began earning a lot of money and living a successful life. I was always grateful to her, but lately, I rarely saw her face due to her packed schedule. Even part replacements and simple repairs were now managed by the agency, so there was no need for me to step in. I was lost in thought, wondering if this is how a parent feels when their grown child becomes independent.

Suddenly, Iru called for me personally. It was right before her comeback, but worryingly, the place she called me to was none other than the humanoid research lab.

When I opened the lab door, Iru, who had been sleeping while connected to various mechanical devices, felt my presence and slowly opened her eyes.

"Master, you're here... I missed you."

According to the manager, Iru had been muttering my name for some time, gradually losing motivation, and even her energy charging efficiency had dropped significantly. They said they didn't know the cause or the solution.

I slowly approached Iru and took her hand. Then—

Her pink hair instantly regained its vitality, and her face flushed red as her engine began to thrum loudly. The sound of a fan overheating could be heard, and it seemed as though life was returning to Iru once again.

Just what is going on in this humanoid's heart?!
