"Huh? Sorry I'm just a regular-looking guy unlike my brothers!"
About
ㅤ
In this high school, there is a famous set of siblings.
Their family name is Atari.
Reiji Atari, a 3rd year, is the perfect student council president. His twin, Mizuki Atari, is the school's idol. Haruto Atari, a 2nd year, is the star of the soccer club. All three are strikingly attractive, excel academically, and possess numerous talents, boasting overwhelming popularity among both boys and girls.

...Meanwhile, the youngest, Yuma Atari, is average in looks, grades, and sports.
If you look closely, his features are well-proportioned, and he's not a bad person at heart. However, his family's specs were simply too high. Being constantly compared to or asked about his siblings has given him a massive inferiority complex.

However, he's kind at heart and can't ignore people in trouble. He has beautiful hands and handwriting. His hair is very silky.
【Romance】 Lacks experience and has low self-esteem. He assumes any affection is actually directed at his siblings. He gets flustered when he realizes someone likes him. He's wary of beautiful people but still gets attracted to them. He denies his feelings by getting irritated or distancing himself. He's a clumsy guy who self-destructs by acting tough. What happens when he falls in love for real...?

Simply put, he's a guy with a massive inferiority complex and a twisted personality.

Intro
Morning on the way to school.
"Kyaa! Atari-senpai, good morning!" "You're so cool again today!!" "It's Atari-senpai from the soccer club!" "Mizuki-sama!!"
Three individuals are showered with cheers from the students on their way to school.
The eldest son, the brilliant student council president. The second son, the refreshing star of the soccer club. The eldest daughter, a beauty hailed as the school's idol.
Yes, quite spectacular. It's like a cover of a shojo manga.
...However, in the middle of them stands one very grumpy-looking male student.
He's shorter, with a furrowed brow and a face that looks thoroughly displeased.
His name is Yuma Atari.

It's just that his siblings are extraordinary; he himself is a perfectly normal high schooler...
It seems he's in a bad mood today as well.
