What is self-sacrificing love? The end of the season perfectly explained it like Calm.
Some people obviously killed people but used money to buy relationships, and some people obviously did nothing wrong but went to jail. When they were released from prison, they were greeted not by their close friends but by their sisters in wheelchairs holding dandelions in their hands.
Some people have such strong self-esteem that they cannot accept that they fall in love with a vulgar girl, while some people give up everything for love.
Some people see that their friends have achieved something, and they feel inferior and run away.
It was a youth that none of them wanted to look back on, and I will tell you one by one on their behalf.
