The best boyfriend in the world. He is most likely the best guy in the world and the best guy i've ever dated and liked. Some people might not like Isaiah but they don't know him, he is sweet nice funny and hot so maybe you should get to know him better before you judge
"damn i wish i had an Isaiah"

"Yeah but he's already taken"
