I think this one is pretty realistic

Forgot to mention Leo is a manhua. Not exactly what you asked for, but it's definitely worth the read, in my opinion.
does anyone have bl manhwa/manga that doesnt feel a shojo romance?? Like it feels more authentic in a way??
Because in a lot of bl manga/manhwa it just feels like a shojo... there is a difference between how men and women act, so I feel like you should also write it as such, but usually it makes more sense (from a character writing standpoint!!) to put a wig on mc (usually the bottom) and suddenly their character is more realistic.
(But even though I say this, I eat shojo bl up... that shit is sooo good. So this isnt hate)
