I'm a Spoiled Young Master, Why Do I Need a System to Make Up for It?

[Not a single heroine. He plays it safe in the early stages, then becomes invincible once his invincible domain appears.]

Cheng Mo transmigrates as the second young master of a marquis's residence in the Great Qian Empire. His elders hold positions in the court and military, his older siblings are highly accomplished, and his younger sister is sweet and sensible.

Every day, he takes a few lackeys to enjoy music at the pleasure quarters, strolls with his birds, and plays with his dogs. He is living exactly as he imagined a transmigrator should.

But the sudden appearance of the Life Regret System leaves him dumbfounded:

[At 38, after your divorce, you remember your childhood sweetheart. You lost touch after you married, and never heard from her again.

Reconnect with Xiao Mingyue. Reward: Mastery of Calligraphy.]

Cheng Mo reads the panel over and over, then glances at the neighboring Loyal and Brave Marquis's residence, deep in thought:

It seems the System showed up twenty years too early. And who is my future wife?

When I'm forty and getting divorced, will I be the one to bring it up, or will she?

As his future wife, childhood sweetheart, and other beauties appear one by one, the System starts to get a little strange.
