After the scene where Doyoung interviews all the Hyunjin's I realized when Doyoung questions why he thought Hyunjin was a quiet person and that he felt more than he had originally thought, I had my eureka moment. When Doyoung had first made the reservation he had said that he wanted to know every little thing about Hyunjin and be the most important person to him. All that Flowerhead did was just take the separate persona's that make up Hyunjin as a whole and make them separate people. In this way, when Doyoung attempts to figure out who is real by becoming close to all of them, he is learning more and more about all the different sides of Hyunjin. By making the Hyunjins believe that only one of them is real and that their fates depended on Doyoung's decision makes him (Doyoung) the most important matter to them.(I had my suspicions about this being the truth when they, the Hyunjins, all had separate hair colors. Mostly because it reminded me of that one Teen Titans episode when Raven turns into multiple versions of herself, I don't think they were her personalities though like in this manwha though. At least that's what I remember, it's been a while since I watched the show. Point is, it reminded me of this.)
The main character is written so well and his actions feel like that of a real person, I've met people like this. The author has such a good understanding of characterization
