Passage: Meanwhile, PK has fallen in love with Jaggu but refrains from telling her because she loves Sarfaraz. Having filled multiple audio tapes with her voice alone, he takes two suitcases full of tapes and extra batteries when leaving for home. He lies to Jaggu saying that the suitcases contain a variety of Earthly noises which he will miss, such as crows and car horns. Jaggu realizes his love for her but does not directly confront him about it. PK does not even look back while going. After his departure, Jaggu publishes a book about him, with Sarfaraz and her family assisting. Her father whistles at her reading, implying that after many years he is very proud of Jaggu.

Question: Who later realizes she loves PK?
Jaggu
