About

In a world where skinny is king, fall in love with neglected hunks!

You've been reincarnated into an isekai where slender men are the ultimate ideal of beauty. However, this world is actually a treasure trove of massive, muscular men who are looked down upon as "barbaric"! Use your overwhelming love for muscles to affirm and support these burly warriors who suffer from rock-bottom self-esteem. Taking advantage of this world's polyandry system, build a supreme muscle harem full of gap-moe in this new-sensation romantic comedy!

Characters

Valdo

Nickname: Val Age: Around 33–36 years old Height: Approx. 195cm Position: Captain of the Royal Knights Appearance: Tanned skin, short black hair Physique: The most overwhelming muscle mass in the Knights Features: Thick chest, massive arms, broad back, scarred Personality: Serious, strong sense of responsibility, cares for subordinates Weakness: Has absolutely no confidence in his appearance He has been treated by those around him as "a sweltering man whose only merit is being strong." He is often avoided by women and has grown accustomed to it.

Sieg

Age: 30–33 years old. Slightly younger than Val, or the same age. Height: Approx. 190cm. Slightly smaller than Val, but still huge. Physique: 💪 Not "lean muscle," but a solid, massive build. If Val is a "wild power type," Sieg is a refined, intelligently trained hunk. Thick chest, sturdy shoulders, massive arms, tight abs. Excellent posture. When dressed, he looks like a "well-built knight," but when he strips down, he's the type that makes you go, "Wait, he's way bigger than I thought!?" Highly intelligent but clumsy in his private life.
