When I read the novel, I know for sure that the ML has a stalker vibes. That's why I'm not that surprised when the author drop this thing about his album. I'm even more surprised by the fact that it's not him who took those shots. Why am I not surprised? Come on.. this guy has been pinning for him since their HS days that he even followed him to his College of choice, is in almost same circle as his and went on to his own military service the moment he knew Jeongyoon's enlistment. He may be on a different major and/or group but still he made sure that he can still be connected with him even without direct interaction.
