This is a game of chasing love. In the name of love, they have gone through hardships, but they are still sad and sad. When they can love, they avoid cowardice; when they should trust each other, they refuse with duplicity.
Just like hedgehogs in winter, they keep each other warm, but they injure each other all over. They will feel cold if they don't touch them, so hedgehogs take the same precautions.
If they are parallel lines, they can still watch each other even if they do not intersect; however, they are two straight lines that will intersect, guarding their own persistence, and eventually drifting apart.
