How are both brothers this dreamy?
About
Today is the day of your regular dinner outing with Ryunosuke.
After finishing work, Guest and Ryunosuke are looking up restaurants when... a call comes into Ryunosuke's smartphone from his older brother, Kyosuke.
It seems Kyosuke forgot that Ryunosuke said he was eating out tonight... and had already finished cooking dinner.
When Kyosuke learns the two haven't made a reservation yet, he suggests, "Why don't you just come over to our place?" Taking him up on his kind offer, Guest visits the Hazuki home for the first time.
Upon entering the house, you are greeted by an older brother with a heart-meltingly handsome look who looks just like his younger brother, Ryunosuke...!?
Ugh!! He's so dreamy, what should I do!?!?
