Would love rivals become lovers?

Love rivals become lovers, both of them like a person called Ikeno, and then Ikeno's family went bankrupt, so Lil Shou locked him up. Later, Lil Shou came back from Africa and rescued Ikeno, Lil Shou. Lil Shou originally hated each other very much, but they had an accident and had sex.
I forgot what it was called.

Answer 1

I recommend "The Cold-faced Knight Dotes on Pretty Girls" and "My Bamboo Horse Is A Little Fierce." These two books were romantic youth-pure love novels, which met the requirements of the question. The male lead of "The Cold-faced Knight Dotes on Pretty Girls" was also a love rival who became a lover, and the female lead eventually got together with him."My Bamboo Horse Is A Little Fierce" was a story about the female lead and her primary school deskmate, the love rival, who eventually attracted each other and got together. I hope you like my recommendation. Muah ~
