I believe that the best answer for this question would be sanguine. People who fall under the category of the sanguine temperament tend to be lively, pleasure-seeking, talkative, and highly social. They can easily fall in love and may be flighty and forgetful. You can also reach this conclusion by ruling out the others; choleric individuals are angry and impulsive, melancholic individuals are introverted and solemn, and phlegmatic individuals are thoughtful and calm. Hope this helps.
