looking for a BL

it was a 3p BL. There was 2 tops a quiet one with black hair and
a smaller one with brown hair (that ended up being a bottom too) and a bottom. The bottom actually had a girlfriend names mimi or mami I think. The brown hair top like the bottom with the girlfriend and the black haired top like the brown haired one and he was lowkey plotting to get with the brown haired top the entire time. Sorry if this is kinda jumbled its all I can remember about it. Thank you for any help~
