why he is the ML and to focus on each of the characters. Although this was already set up since the start but wouldn't really be noticeable until you begin to understand the characters better, so it definitely wasn't a random decision that the author pulled out of nowhere (I assure you, quick second-hand spoilers aren't good to making judgments whatsoever). Plus the cover is not an indicator of who the ML is, especially since the novel covers features all of the main characters and even supporting characters. Also, the upcoming arcs this season will be focused on the ML and other characters like Woo Ju-In from what I've heard.
