Only two of the printed lines actually show this as an ending, and in both it is a relaxed, slightly regional squashing of 려고, meaning intending to or about to: the one asking what he was about to say, and the one about having got them for Na Eun. The rest of the lines are sound-alike matches where the same letters fall inside another word entirely, including a nonsense catchphrase, the word halal, a hula chant and a brand of bug spray. Two lines are thin evidence, so treat the reading above as likely rather than settled.
