This was surprisingly hard to find, most tops really do have either black, blond or variation of silver. I think its because the top is supposed to be the "special" looking one and brown is boring
Wait sorry, wrong post.
Really specific but any good BL reccs where the seme has brown hair lol i feel like it’s always black blonde or white with these tops??
