I'm looking for this one shot promo manga that I forgot the name of. FL has green hair and was adopted by the villian(?) 's family and now the stepbrother is into her or smtg. The art is really pretty and all I rmb is that FL said she'll reward the ml and he was like ok give urself to me as a reward.
I think the one your looking for is called please throw me away.
