The two met in a foreign country because of work, and it was a coincidence. One has just graduated, doesn't understand anything, and needs care at all times; the other has been drifting away for ten years and believes in self-improvement and independence. Two people work together, one is completely disadvantaged and has to rely on and be forced to grow up; the other is a sharp-tongued person who scolds, hurts, dislikes, and sinks unknowingly. This is a random story.
