Wedge:
Green? They are all a group of college students who are about to graduate and still retain their youthful thoughts. Although they were all born in wealthy families, they still have that innocence.
Red? They will gradually take over the family business, and in the process, they meet the other half that makes each other's heart beat. They learned to accept reality, learn to persevere in the face of difficulties, and learn to persevere in true love.
This is a process of transformation, although painful, it is still full of laughter. This is also a maturation process that allows them to understand more principles of life and strengthen their attachment to their significant other. It is not until we have experienced a lot that we can smile similarly and understand that there is a meaning hidden in each other's smiles that just having you is enough.
