"Love hard" is open to a million interpretations, and it doesn't fit nicely into Japanese when "love" itself doesn't always have the one-to-one value we would like it to have. (Romantic love? Familial love? Love for a pet?). And performing any of these acts of love in a "hard" way.... well, again its liable to turn into a silly Japanese sentence (as it has done above in my attempt).
To convert into vertical, copy and past the above into word or excel and manipulate from there as you like.
