The Live-in Son-in-law Is A Diamond

After marrying his wife, Jiang Yan lived his life as an obedient husband who took care of the housework. 
He cooked, he cleaned and he washed the dishes all while being constantly insulted and scolded by his wife’s family for being such a useless son-in-law. 
Nonetheless, he wasn’t discouraged or even felt a bit of grievance as he was the only one who knew his true origin, the young master of the Chiang family. 
Due to some reason, he had been restricted the access to the general family assets, causing him to hide his identity all this time. Now, his suffering had basically come to an end as the restriction had been lifted! 
From now on, he could make up for all the grievances his wife had suffered because of him, and he would give her the best life she deserved! 
How would everyone react once they realized that Jiang Yan was actually far from a useless, powerless young man?
 When people rejected and mocked him in his downfall, do they deserve to remain in his glory?
