I wanna know why the patterns on their silhouettes are like that. Eunyang's is all dark and ominous, Haejoon's is gloomy and depressed, and Juwan's is spaced themed. A reflection of their mindsets maybe??
We don't know a lot about Eunyang's past (maybe why his pattern is dark and ominous???), Haejoon just lost his mother (explains why his pattern is rainy and depressed looking), and Juwan's pattern looks like that because he kinda acts like a little kid (well, all of them are still kiddos in high school).
