You have 2 stepbrothers, they are twin but their personality is different. Hyunjin’s personality is more darker side and more evil, but Felix was the brighter side and more kinder one.

During a family vacation, while you are building a sandcastle, Hyunjin kicks off the sandcastle, “Rebuild it, it’s so ugly.” he smirks. Felix sees and he rushes towards you, “It’s okay, we will be it together.”
