Love or Hate is a series that just started out that you might enjoy. The main character, Haesoo, isn't able to make any of his relationships work because he's still head over heels for a guy that he has a complicated romantic past with named Joowon. Although Joowon is still in Haesoo's life, he's not willing to seriously commit to a relationship with Haesoo, but instead uses Haesoo's feelings to his advantage to manipulate him. It has some of the best writing that I've seen in quite a while, and the art is gorgeous, so I highly recommend it.
