This can be regarded as a continuation of "If Happiness Is Only Like an Illusion", and there will also be some extras to help clear up your doubts.
Since I wanted to write a short series of articles, I didn't put them together with that one.
Haha, although the "Happiness" article is too far away from the fandom, I will try my best to write future stories and understand the essence of the fanfiction.
Hope everyone likes it!
