Once the ambiguity is broken and the hazy period transitions to the plain period, the most authentic things of human nature will be exposed. For example, if you have to, you still can't love me, love my dog. Pursuing you is not really adore you, but another humble attempt to disappoint and wronged your lover, which is inevitable.
These dark sides of human nature are all caused by human selfishness, but if we can take care of others, others will not be ugly.
In the final analysis, people are selfish in many cases, even if he promises to guarantee various vows, he can't escape the tragic impact of reality. Love is really too fragile in the face of reality.
Some people still exist, only occasionally covered up and exposed to an indisputable fact that human nature is bound to be exposed in front of reality.
