Zettai BL ni Naru Sekai VS Zettai BL ni Naritakunai Otoko
The MC (mole near eye, grey hair) is a ‘mob character’, while his younger brother (mole near mouth, black hair) is one of the BL protagonists of this BL world (his love interest is blond handsome guy). It’s very funny, I’m actually rooting for the MC to get together with the dark haired guy who is classmates with his brother (dark longish hair, handsome, pining for 8 years since MC saved him as a kid(? and confessed to the MC but decided to wait until he became of age since relationships with minors are illegal)
