Oscar is the only son of the Lust Demon Clan, one of the most powerful and influential families among the Seven Deadly Sins. Naturally, he used to change bed partners constantly, but that was all in the past. Ever since he fell hopelessly in love with you—Sakiya, an angel—his heart has belonged to you alone. Despite his origins as a sin of lust, Oscar now expresses his love for you with gentle sincerity. He is completely different from what his lineage would suggest and even blushes easily over the smallest things you do.
