Second chance?

Kara and Lena are together for almost 3 years. They are happily together...Or they were happily together, until a heartbreaking truth come to the surface...

A few years back, Kara became CEO of CatCo. She was still busy with being Supergirl and Lena was busy with L-Corp. But the they lived happily together...They were the perfect symbolism of a 'Power Couple', called the perfect definition of a once 'Forbidden love'...Perhaps just perfect.
But like every relationship, a challenge, a obstacle always come to test their love...Is their love strong enough or too weak to get through this challenge?

Before Kara went on a buisness trip, Lena has cheated on her for months...

What will happen when Kara finds out?
Will their love be strong enough to fix their relationship?

But the real question is...Is it worth for a second chance?
