A relationship that doesn't need to boil over, two people who just fit together.
Lu Yanzhao was divorced once, and his ex-husband said he was suffocating.
Shen Ruohan has never been in a serious relationship. He thinks love is too troublesome.
Later they got together.
Lu Yanzhao is not clingy, and Shen Ruohan is not committed.
But those waiting in the corridor late at night, the clenched fists outside the operating room, and walking side by side in the wind and rain, are heavier than any promise.
Some feelings don't have to boil, just keep them warm.
