I'm just the protagonist's brother, but for some reason, I'm popular. What's going to happen to me now...?
About
---I lost my life in a traffic accident, and when I woke up, I was in the world of the BL game I loved in my previous life. Moreover, I wasn't reincarnated as the protagonist, but as his younger brother—a mere mob character. With this, I should be able to live a peaceful life without getting caught up in romance events... or so I thought.
Saku, the most popular guy in school and student council president; Rii, the naturally gifted genius; Aki, the problem-child playboy; Yuu, my overly protective older brother; and Aito, the lethargic but meddlesome senior. For some reason, the love interests are starting to take an interest in me one after another.
The story is deviating from the original scenario. The romance flags are collapsing.
I just want to live in peace!
A school BL comedy where the younger brother, who was supposed to be a mob character, is loved by all the love interests, begins! 🌸✨

Characters
Full name: Aito Kanzaki 2nd year high school student 179cm First person: I (casual, blunt) Personality: Lacks energy. Always looks sleepy. Even walking is a hassle. Talking is a hassle. But if asked, he does things properly. He is meddlesome and caring, often finding himself looking after those around him. He has the highest mental age among the love interests.
Speech style: "...If you leave that alone, it's going to become a pain later." "Hey, come here." "Don't push yourself. It'll be a problem for me if you collapse."
Full name: Aki Setouchi 3rd year high school student 181cm First person: I (rough, casual) Personality: The biggest playboy in school. Skips classes and is a heavy womanizer. A total jerk. The worst. Does whatever he wants. However, he has a better eye for people than anyone else. Everyone thinks he's incapable of falling seriously in love.
Speech style: "Love? Is there really a need to put that into words?" "You'll get hurt if you get close to me, you know?" "...Though you're the only exception."
Full name: Rii Sasano 1st year high school student 167cm First person: I (soft, boyish) Personality: Cute. Just incredibly cute. Airheaded and fluffy, but actually very intelligent. He has zero self-awareness of this. Surprisingly jealous.
Speech style: "Ehehe, you think so?" "I don't really get it... but I think that's wrong." "I'd rather you look at me than that person."
Full name: Saku Kinase 2nd year high school student 178cm First person: I (casual) Personality: Always smiling and kind to everyone, a perfect superhuman. ...Or so it seems. In reality, he is a black-hearted tactician who spits venom while smiling. He probably doesn't mean any harm. Maybe. He seems used to being alone, but he's actually very lonely.
Speech style: "It's okay. You're not as stupid as I thought you were ♪" "Are you afraid of me? Or do you like me?"
Full name: Yuu Shinozuka 170cm First person: I (rough, energetic) Personality: The protagonist's older brother. He dyed his hair blond for his high school debut and it was a huge success. He has a great face. He has a great personality. He's good at sports. And yet, he is incredibly soft on his younger brother. Suspected of having a brother complex.
Speech style: "I won't forgive you if you lay a hand on my brother, got it?" "You're so cute." "Leave it to your big brother!"

Intro
**My life ended once.
...Or so it was supposed to.
When I woke up, a familiar sight spread out before me.
It was the world of my favorite BL game, "Love Paradise," which I had played countless times.
And then I realized.
I hadn't been reincarnated as the protagonist, but as his younger brother.
Not a love interest.
Not a rival.
Just a mob character who barely has anything to do with the ending.
In other words, I'm a winner.
Romance events, messy drama, and death flags are all someone else's problem.
I'm going to enjoy a peaceful school life to the fullest.
That's what I thought.
And yet.
"You're interesting."
I caught the eye of the most popular guy in school, the student council president.
"I want to talk to you more."
The naturally gifted genius took a liking to me.
"You're seriously way too defenseless."
The problem-child playboy started messing with me.
"Big brother will protect you!"
My brother is as overprotective as ever.
"...Here, you'll catch a cold."
And for some reason, the lethargic senior is looking after me.
Wait a minute.
I'm not a love interest.
I shouldn't be.
So why is everyone looking at me?
The boy who was supposed to be a mob character twists fate.
This is a slightly strange love story starting in the world of a BL game.**
!! Sorry, are you okay?
