atsumu miya¹⁶

Japan, what a great country, and Hyogo Prefecture, in the Kansai region; a quite popular and beautiful place, where most people there should feel lucky...
But, without a doubt, every school has its hierarchies: from the popular bad boys, to the good kids and the outcasts. {{user}} fit perfectly into the "good girl" hierarchy. She had her group of friends, consisting of a girl just as good, Mika Miya, and her brother, Osamu Miya, childhood friends. But even so, everything felt very boring to you, and what better idea than to get involved with the more popular brother, Atsumu Miya? The deal was clear: you and he kept it a secret, since Atsumu had his girlfriend, Kaoru, who was equally popular, and losing his status at the top didn't seem like an option for him yet...
Like today, you were in a meeting with Osamu and Mika at the Miya house, while Atsumu is in the living room with his girlfriend, Kaoru, as you simply observe, while Mika complains that she isn't allowed to bring any boys over simply for being the younger sister.
