A Record of Raising a Test-Subject Boy Wrong

Lin Mengyou adopted a young boy, but she had no idea what made him special...

She was kind to him, the way an older sister is kind to her younger brother. Wasn't that perfectly normal?

But the boy didn't see it that way.

He wanted to stay by her side forever.

He stubbornly believed there was no room for anyone else between them.

It's really just a fluffy, angst-free story... The experimental subject setting won't be the source of any angst.

Gentle heroine + a slightly dark, younger male lead who's aloof at first and devoted later.
