Ahem~
This article is a campus article for brothers. As the title states, it is thin, light-colored, and slow-burning.
The protagonist learns about his life experience by chance, but his brother, who is one of the puzzles, does it despite knowing that the facts are contrary to common sense.
In fact, the protagonist is not unaware of his brother's actions and thoughts, but he doesn't know how to respond. As a result, he just blindly indulges his brother's strong possessiveness.
Ah, hey, what's going on... (Pun intended)
The thing is, I really hate writing attractive copy.
