Introverted Sensing (Si): Cho follows through with her commitments. When she accepts Cedric’s invitation to go to the Yule Ball together, she stays true to her word, turning down a later invitation from Harry, with whom she really wanted to go to the ball. Additionally, she never takes the initiative to ask Harry to the ball herself (classic Si traditionalism). Cho is loyal to everyone she knows; she doesn’t stop talking to Harry even when most of the Wizarding World regards him as “disturbed and dangerous,” and when her best friend, Marietta, sells out the defense education group that Harry leads, Cho refuses to cut ties with her. Cho has a tendency to remember past instances of rudeness, like when Ron insults her Quidditch team (Si-Fe). During her one Quidditch match against Harry, Cho lets him search for the Snitch while she tails him.
Extroverted Feeling (Fe): Although Cho is not a slave to social expectations, she cares a great deal about what other people think of her. When she forms a relationship with Harry after Cedric’s death, she worries a lot about about what people would say about it (especially because Harry was so intertwined with Cedric’s death and the aftermath thereof). Cho is open with her emotions; she smiles at Harry upon seeing him for the first time, she cries publicly when she talks about Cedric dying, and she yells in her defense of Marietta. Although Cho actually likes Harry more than Cedric, she is comfortable becoming Cedric’s girlfriend after spending time with him.
Introverted Thinking (Ti): When Cho suspects that Harry and Hermione might be more than just friends, she chooses a very roundabout way of questioning Harry about the matter. She goes to the trouble of understanding why Marietta would betray the defense group (including herself). Cho is a Ravenclaw, implying that she is intelligent and analytical, but she can have trouble using spells in practice even when she knows the theory (in particular, she states that she had problems with the Stunning Spell).
Extroverted Intuition (Ne): While Cho is starting her relationship with Harry, she is worried about a hundred things that could go wrong in her life. When Harry is teaching her how to defend herself, Cho wonders whether Cedric would have survived if Harry had taught him as well. Cho can sometimes jump to erroneous and very negative conclusions about Harry’s feelings, especially when Hermione is involved in the situation, even tangentially.
Note: I went with the popular opinion on this typing, but I considered ESFJ as well; Harry’s reason (excuse, really) for not asking Cho out right away was the fact that she was ALWAYS surrounded by her friends. Still, her Fe just doesn’t look strong enough to be her dominant function; even though she cares about public perception, she doesn’t let it dictate how she lives her life (especially in how she deals with Harry when he is at the lowest point in his popularity). Cho is just a very social introvert.
