What does it mean to know each other in winter and be accompanied by four seasons?

"Meet each other in winter and stay together in four seasons" means that they meet in winter and stay together every day after falling in love.

Love is beautiful, because I have personal experience:

When I was in college, I experienced a beautiful love. Coincidentally, we met in a snowy winter.

I remember very clearly that day, it was snowing heavily outside. As a student, I am still curious about snow. Then I walked around the campus in a thick down jacket and felt the beautiful scenery of pine needles wrapped in silver. After a while, a boy came not far away, wearing a black down jacket. When they walked to the opposite side, they looked at each other, and at that moment they had eye contact and a good impression.

Soon we will be together. He is a warm boy, he is good at taking care of people, and he is also a very sunny big boy. There seems to be no trouble in his mind, but humor exists every day, which is also a variety of fun for me. When I need to be quiet, he will accompany me, that is, the kind of silent companionship without complaint.

Yes, good love will never be forgotten. Even when it is quiet, I will think of him who accompanied me through the four seasons.
