@Gundamotaku The whole point of this manhwa and others like this is character development. I would read more than just the first few chapters to start crafting judgement. I think you'll be satisfied at the MC's true nature that isn't displayed early on.
@Cheso_No_Akuma Well, he's certainly not displaying full frontal. He's shy about it, so yeah "hiding it" is the wrong phrase to use but he's definitely not being open about it. Otherwise, he'd maybe directly communicate with her to see why she's forcing a smile. THat's my take though.
