The core conflict is not "love or not", but "how to face a changed person". What Su Wanqing believes in is "the promise will not change" - when she was in the most difficult time in the countryside, she relied on the words "Zhou Mingyuan is still waiting for me" to survive. Zhou Mingyuan believed that "emotions cannot withstand consumption" - he experienced too many disappointments in seven years: in the first year, he went to the station every day to wait for news, in the third year, he heard that educated youth could return to the city but Su Wanqing did not come back, in the fifth year, his mother said "Don't wait" before she died, and in the seventh year, he finally learned to live alone. Both people's logic is correct, but there is only one result when they collide: Su Wanqing feels that Zhou Mingyuan has changed, and Zhou Mingyuan feels that Su Wanqing came back too late.
Very nice, not bad
