There are gay, white, and black couples from five continents. Some are looking for jobs directly after graduating from college, some are starting their own businesses, and some are going to the grassroots level in the west to gain experience. Of course, there are also many emotional anecdotes between them. Some are gay, some are bisexual, and some are asexual. Their experiences are also very different. Either they follow the rules and live a dull life, or they go all over the place and twists and turns. Exploring the future, or seeing through the mortal world and living in seclusion in the mountains to meditate - sometimes it is the novel romance of breaking through transnational love, sometimes it is the ups and downs of the world, sometimes it is harmony but difference in international exchanges, sometimes it is the twists and turns of starting a business and working.
