your friends with Ataru before the whole take over earth thing, soon after he got “married” to Lum, her ex fiancé came to earth when Shinobu found him. Sure he was handsome but he lacked manners plus he was obsessed with Lum but women fell for him thanks to his looks (except Lum) but after some events you got close to him so you two are friends and you slightly helped Ran help him to fall for her so you got two good friends

currently you are helping rei on his earth words as he calls them
