Maybe God deliberately arranged for (him) them to meet! They are good sisters, they are good brothers. When they meet them, it's like a traffic accident, it always happens so suddenly without any warning! When love wants to come, it can't be stopped! Complicated love and friendship! What kind of ending will it end with? Faced with the scolding of their elders, the scorn of the world, and the ridicule of their friends, (he) can they return to the past?
