DANGEROUS LOVE:Brother-in-Law

Initially Sonia and Edward's marriage was happy because they both loved each other. They decided to have sex after officially getting married.
But apparently Edward's ability in bed matters did not satisfy Sonia, it made her not in the mood to serve her husband.
But Edward, who is highly educated and loves Sonia, obeys all the wishes of the girl he loves, even though he treats her arbitrarily.
Until the temptation of marriage came, when Edward's brother named Steve came from Holland after studying there for a long time. Sonia felt that there was someone who could listen to her heart, namely Steve. In the end, the relationship between brother-in-law and sister-in-law had crossed the line of reasonableness.
Sonia is more interested in Steve who can satisfy her bed matters. Then what about Edward, would he know? or can he accept and forgive Sonia?
