Can you recommend me BL that started out as friends? Like legit friends not the "you're my friend but you're so sexy dayum" or the "i saw you naked and i love your nipples". Legit friends with no sexual innuendo (plot wise). Preferably where initially both side did not harbour any romantic feelings, not necessarily. And they don't have to be close friends; just friends from the same circle is ok too.
(sex is ok, just not the trigger for their change in relationship)
