Prison boys (Tetsu x Nagi) yaoi/smut

the story is based on the game "prison boys" by
ESC APE by SEEC
I really love that game. The game is a
"mystery novel + escape game" you'll really love it
the game is about a high level police officers who eliminate all the rebels of the country(japan). There was a boy named Tetsu akatsuki. One of the junior officers. He is a orphan that is adapted by the Saeki family a noble family(not sure but that family is more on political) Nagi and his big brother is the childs of the Saeki family who chooses to be a officers. Tetsu and Nagi are junior officers and their big brother is a senior. the game's mystery starts when their big brother died hanging with a rope.
Others think it was a suicide but the two boys think it is not. So they try to solved the mystery of their brothers death................it is a long story........the game had 5 chapters.........at first the game is not interesting but when you are on the middle of the story, the story will be interesting until you finish it.
😭😭😭😭😭😭 I wish there are more chapter because the game is really interesting.......by the way this fanfiction will be focussed on the game like behind the scenes. the game will be morw on fluff and some smuts so please be patient to my grammars

U recommend you all to play :
"prison boys[mystery novel / escape game]"
pls play that game😭😭😭😭😭😭
if you are familiar to the characters this story will be more interesting😂😂😂
