So the real hyung is both, basically the hyung whos rougher with our mc is the real hyung, the hyung that we see whos kind and nice to mc is his other personality, kinda like bipolar, the 2nd hyung is all his bottled up emotions, meenwhile the 1rst hyung is the nicer one who always wears a smile and keeps his emotions hidden, due to the fact 1rst hyung fell for mc, he also tried to bottle up his emotions for mc, leading to 2nd hyung to come out of his shell, as we saw inside hyungs consiousness we see different versions of him, seemingly his disgarded personalitys, emotions bottled up, in a form of himself, from what ive seen, the second hyung is created by himself trying to hide his real personality and keep a fake smile, these two hyungs, are one person, no difference, just a smile, and fear of being judged for who he actualy is, leading to two personalitys, hyung no.1 is the fake one, physically one body one face, and a mask with a smile on it
