if you're interested i have a list for tan bottoms. some of them are tan by korean beauty standards and some have stereotypical looks and personality for an uke, but they're mostly tan and fit. if some covers don't look right, the description lists which specific chapters are about a tanned uke. there's some decent stories, but also quite a few where the storytelling is either bad or nonexistent, but a homie is desperate so a homie makes do with what they got.
