How do i start a romance in dragon age 2?

plz help|||i think you have to have them like you completely|||You can romance Anders, Fenris, Merill, or Isabela. Always choose the dialogue option with a heart icon whenever it is available. This will make you flirt with them and begin the romance. Then work on either getting them to full friendship or full rivalry, do their personal quests, and give them their gifts. You can find guides online if you need help with a specific character you like.|||Romance begins with tire irons. Once a tire iron is in the relationship, one thing just leads to the next. It's magical.
