A few days after Jane and Daniel got together in that caffeine talk, after Jane had been surprised with the news that she was meeting Daniel's parents, after the awkward meeting and after he sincerely apologized for the awkward behavior his family put up in front of her…
(it was hilarious, trust me. Daniel was a Mama's boy but his parents seemed to have fallen head over heels for Aliya and neglected him)
…she got a call from her ex-boyfriend who broke up with her. He had refused to tell her the reason at the time of the breakup but now he was ready.
He told her he didn't have long to live and so that was why he decided to break up with her. He didn't want to leave her so abruptly but then he thought of how pained she would feel and maybe blame herself so he decided to tell her the truth.
