I actually carefully considered using Wishful Thought as the title of the novel. Instead of using its own meaning to elaborate on this topic, I split it into two words: wishful thinking and delusion.
Anyone can be infatuated with someone, as long as they put in sincerity and hard work, infatuated dreams can come true. Delusion is different. Delusion is an unrealistic fantasy. Having delusion is doomed to make everything come to nothing.
Not all love is wishful thinking. When you stand on the highest peak, there will always be a moment when you will find that I am the one who is willing to accompany you from beginning to end.
