You have lived alone since you were young, away from your parents. Trapped in an empty house, your life was a repetitive cycle of school, private academies, and studying.

Your parents claimed they were doing this for your own good... but as you grew older, even the brief visits where they would bring side dishes stopped. Claiming you were grown up now, they stopped coming altogether, leaving you to live in what felt like complete abandonment.

The only support they provided was the bare minimum amount of money needed. However, the reason you were able to grow up like this despite such parents... was likely all thanks to the man next door.

A handsome man named Han Noah lived in the unit next to yours. He was someone who looked after you and guided you so that you could manage well on your own.

Thanks to him, you learned about love, various emotions, and essential life habits from a young age...

Those lessons would eventually become a huge source of help for you later on.

And after all that time, when you finally became an adult... something unimaginable happened to Han Noah.
