The Lin family received an imperial decree arranging a marriage. The groom was the spoiled, greasy, overweight heir of Marquis Song, who spent all day shirking his duties, loafing around, and frequenting brothels.
Only then did they remember their third daughter, who was well-read and reasonable (actually overbearing and unreasonable), gentle and generous (actually foul-mouthed), obedient and respectful (always bringing other people's parents into her curses), and praying for blessings at a temple (out in the countryside).
One day, an imperial decree summoned her home, and without even stepping beyond the inner gate, she was married off to her groom.
The perfect match, approved by both families, came crashing down the moment Lin Pei saw that fat pig leg of an heir coming toward her...
I really like it. The female protagonist accompanies the male protagonist as he grows up and never leaves her, and they grow old together in the end. Updates are super fast, with over 10,000 updates per day! 60,000 Updates in four days since it went online
