In Secret Summer, your dad has a lucrative business, and you have been chosen as his successor. You were swept away and taught how to run the business. During a phone call, you heard your mother crying on the other end. You figure out a way to go home and see what's going on. The reunion with your family is only possible if you're willing to stick your neck out and risk everything. It's not going to be easy, but your mom's safety and sanity are what's at stake.
