main points
We are so young and beautiful that we have always regarded love as our habitat. Some people say that the space of love is actually very narrow, so small that it can only accommodate each other.
line
Parallel, crossing, waves, this is not love, but our wonderful life. Some people say that to make the love line longer, besides courage and belief, at least some considerate details should be added.
diamond
You and I, angular, constantly collide in love. Some people say, don't dream of cultivating love into a regular polygon and paying many unfair specimens.
circle
No matter how cute the waltz is, it can't be separated from your cooperation. Some people say that love is an arc, pulling each other until two people form a beautiful circle.
heart
Although love is the formula of two hearts, geometry has never taught us how to calculate its area. Some people say that love is not as complicated as mathematics and geometry. As long as we love each other, our hearts can be connected. (For reference only, you'd better make it up yourself)
