It's best if the second female lead is the male protagonist's sister, and the second male lead is the male protagonist's rival. I'm looking for it online!
The main plot is good-looking, and the sub-CP is interspersed with the main plot.
My favorite pair of secondary CPs (Wen Haochen × Bai Yu, it should start from Chapter 1368, it is also discontinuous, but you can slowly jump to chase it, this pair is chasing his wife in the crematorium)
22 "After losing the love bet, Ou Shao's aloofness collapsed"
Wen Yuxi (the little princess of the Wen family) & Ou Linchen, the male and female protagonists
It's very sweet and the characters are nice.
Zhao Zhiyao & Wen Yuhao [The eldest lady of the Zhao family VS the heroine's brother] The Zhao and Wen families are family friends.
Guan Xirui & Wen Yubo [The second young lady of the Guan family VS the heroine's brother] The Guan and Wen families have grudges, and their relationship is bumpy, but it's quite sweet.
There are quite a lot of CPs in it, and there are also brothers of the male protagonist who are not listed. If you want to see it, you can go and see it. The writing style of the novel is delicate and the sentences are fresh.
