What does the cartoon "Not Puppy Love" show?

I think what this cartoon wants to express is that "puppy love" is just a simple, ignorant and precious emotion in adolescence. Like the tide, it is a normal phenomenon, not a scourge. Therefore, parents and schools should be more tolerant, pay attention to children and give them correct guidance and due respect. Instead of chasing it blindly, it will only be counterproductive.
