Crystal and Toshiro

here are my sims, Crystal and Toshiro they have been dating since high school, funny thing is Crystal's father doesnt like Toshiro so he picks fights when ever he can with Toshiro but Toshiro always ends up kicking Takashi's ass and winning xD and the thing is Toshiro and Crystal dont fight at all. And Toshiro doesnt cheat on her nor does Crystal you can say they love each other so much
