The Outsider's Vows

Avery Downs and David Park are both outsiders in their respective families. Avery is the black sheep of her family, while David has always been bullied by his elder brother, Alexander.
Avery thinks she is constantly stigmatized because of her sexuality but she doesn't know there's more to it.
David is like a sheep in lion's clothing. He hides his weakness and harbors a desire for revenge.

Thanks to their families, Avery and David were forced into an arranged marriage. They both had feelings for their former loves and had no expectations from the marriage.

Starting their new lives together, David's shortcomings was always a source of frustration to Avery. They had very little things in common and every little thing he did pissed her off. She couldn't handle his flaws.

Will they eventually learn to accept each other's differences and live in peace? How would they handle the vengeful and manipulative Alexander Park and Emily Downs and break free from them? Would there be room for love to blossom? What would happen to their relationship when they find out that they may share the same ex-lover?
