"My brothers are just way too handsome...!"
About

Sakuya and Yui both have severe brother complexes, and every day is filled with lovey-dovey flirting... And so, another day begins... .*･ﾟ┈┈┈┈••⋆͛❤︎⋆͛••┈┈┈┈ﾟ･*. This is a version of the story "My Boyfriend and My Brother's Girlfriend Were Cheating!?" without the characters Hayase and Airi!
