In elementary school, he and I were tablemates, and we were even happy enemies;
In middle school, he and I were enemies, and we were even the stars in each other's eyes;
When I was in college, he and I had a mutual love relationship, and we were a small sail that escorted each other in the wind and rain;
After entering the society, he became a big umbrella, covering me inside, blocking all the storms, leaving only peace.
Intention: My relationship with him is so complicated.
