Mr. Mu appears aloof in public, but secretly proposes marriage and kisses.

[A down-on-her-luck but resilient heiress VS. A cunning and scheming young master from the Beijing elite]
Su Muran and Mu Tingshen's whirlwind marriage was an accident.
She was a fake heiress from a wealthy family whose true identity had just been revealed, and he was just a poor boy she had once sponsored.
Su Muran found Mu Tingshen and said, "One million. Marry me, and we'll divorce in six months."
They maintained a respectful relationship for six months, until their final night, when they lost control after drinking…
Su Muran left behind a divorce agreement, and the two met again three years later in a foreign country.
Mu Tingshen slowly spoke, "Ten million. Be with me, and we'll divorce in six months."
Su Muran always felt that Mu Tingshen, the current crown prince of Beijing's elite circles, was simply unable to swallow the anger he felt back then.
But she treated him with courtesy, so why did he keep asking her for sex every day?
When Su Muran was confessed to by a man again, Mu Tingshen, jealous, pinned her against the wall and bit her lip until it bled.
The proud and domineering man, tears streaming down his face, held her tightly and pleaded humbly, "Ranran, could you... love me just this once?"
