it is Accusative because the verb любить is a transitive verb and requires the direct object (complement) in the Accusative.

You thought it could be Genitive only because ANIMATE MASCULINE nouns have the identical inflexions both in Genitive and in Accusarive. e.g.:

У меня нет БРАТА (Gen.) --- Я люблю БРАТА (Acc.)
У СЫНА есть гитара (Gen.) - Я люблю ( вижу, слышу) СЫНА (Асс).
Это книга моего ОТЦА (Gen.) -- Я люблю (уважаю, помню) ОТЦА (Acc.)

You must have remembered that the Genitive of MASCULINE ANIMATE NOUNS is identical with their Accusative, and hence, your question.

You are doing great! Keep hanging there, and blessings rom above in your studies!
