The best match is "Marriage first, love later". Two heirs of a top wealthy family got married by contract in order to deal with their families. Each thought the other was a "little pitiful". However, after the marriage, in the process of hiding their identities, playing tricks on each other, and pulling each other to the extreme, they staged a ridiculous "rookie pecking each other". In the end, they both fell out of love and fell in love at the top.
