The Daily Life of a Puberty Syndrome Sister and a Flirty Older Brother

A younger sister who has lost the ability to show emotion, and her older brother, a struggling novelist.

Like flint and steel, what kind of sparks will fly when the two rub shoulders?

It's pretty much all sweet couple stuff from beginning to end.

Whenever you have time, try reading a few chapters. If you've had your fill of sweetness, set it aside for a while. Then, whenever you're feeling down, you can pick it up again and watch the siblings show off their affection for each other.
