How Did the Archenemy Become the Master?

Lin Xiaohe and Yelena have been enemies since childhood. The mixed-race beauty with blond hair and blue eyes always used the excuse of "being born two hours early" to domineeringly ask her to call her sister. She insisted on being the mother when playing house, and even competed with the neighbor's little brother. Shen Xiaochu has always coaxed his two sisters since he was a child. He really can't understand why the two sisters always fight back and forth. But when Yelena suddenly put away all provocations, Lin Xiaohe panicked: Wait, this feeling of accelerated heartbeat... Could it be that I have fallen in love with her? Until one day, the other party approached his ear with a sly smile: "I have been waiting for this day for a long time." Lin Xiaohe was completely confused by this sentence - wait, this plot is going in the wrong direction! When did the script of mortal enemies turn into a sweet game between owner and puppy? !
