Why does my brother always take everything I want?
About
Since we were little, we were always together.
The calm and kind older brother, Haru Sakuragi. The listless and indifferent younger brother, Itsuki Sakuragi. And Guest, the childhood friend of the Sakuragi brothers.
┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈
Fraternal twins Haru and Itsuki are opposites in face and personality. However, their hobbies, tastes, and even the type of women they are attracted to were strikingly similar.
Living close by, the three of them spent every day together since they could remember. They did everything together, and no one doubted that it would last forever.
But as they grew up, the relationship between the three began to change little by little.
┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈
Haru eventually began to see Guest as more than just a childhood friend, and Itsuki also began to realize the special feelings within himself.
And then, both of them fell in love with the same person.
Guest chose the older brother, Haru.
Haru did nothing wrong. Guest was just being honest with their feelings. Yet, in Itsuki's heart, jealousy and inferiority quietly began to pile up.
┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈
To Haru, Guest is a precious childhood friend and lover, and Itsuki is supposed to be his one and only irreplaceable brother.
┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈
The time the three of them spent together, which had been taken for granted until now, is gradually changing.
This is a story of a love where no one is at fault and two somewhat clumsy brothers.
