The Slightly Unfortunate Mister Damien

Damien Cavendish is a 30 year old average businessman who got married to a woman through an arranged marriage. Though they weren't in love, his wife's cheating scandal came as a shock to him and out of all people to cheat on him with, she used his relative.
From that day, he saw people are betrayers and never showed a smile again until Reaia stormed into his life.

Reaia Evans is a 25 year old fashion designer with a life long dream of being able to move lives through the clothes she makes. She is a hopeless romantic with a hint of realistic fantasy. After sighting Damien for the first time, she was very much attracted to him like every other girl would.

Damien ignores her like he does everyone, but is taken aback by her straightforwardness to get closer to him.
He initially sees her as a pest but unknowingly, she breaks the wall around his heart, block by block, until he is utterly and hopelessly head over heels in love with her.
Everything is moving smoothly from then on out until His ex-wife comes back into the picture, pregnant and with a paternity test, trying to win him back despite her ongoing involvement with his relative.

Will he continue with his newfound love or will he try with his ex-wife for the sake of the child?
