## My Thoughts on Hobby Modification App ### First Impressions "Hobby Modification App" immediately grabbed my attention with its unusual premise. The idea of an MC with an app that can, well, modify hobbies, sounded like a recipe for either hilarious chaos or disturbing psychological exploration. After diving in, I can say it's definitely leaning towards the latter, in a way that's both captivating and unsettling. ### What Works Well The characters are a major draw. The MC is fascinatingly detached, almost sociopathic, in his approach to using the app. He's not your typical blushing, dense protagonist; instead, he's analytical and driven by curiosity, viewing relationships as experiments. This makes for some truly unique interactions, particularly with the female characters. The heroines themselves are surprisingly well-developed, feeling like more than just cardboard cutouts. The gradual descent into obsession, especially with one particular character's yandere tendencies, is genuinely gripping. The erotic scenes, while frequent, are apparently well-written and tied to the psychological development of the characters, adding a layer of depth beyond simple titillation. The concept itself is strong, offering a dark twist on the usual wish-fulfillment fantasy. ### Areas of Concern While the character-driven focus is a strength, it also seems to be a point of contention. The plot feels underdeveloped, with the story focusing heavily on character interactions and erotic scenes at the expense of world-building and overall narrative progression. I can see how this might frustrate readers looking for a more complex storyline. The translation quality seems to be a bit inconsistent, with some confusing passages and awkward phrasing. Also, the MC's initial discovery that one of the heroines already liked him before he used the app does feel like a bit of a plot shortcut, undermining the purpose of the app itself. ### ⚠️ Spoiler Warning Some readers have pointed out that the MC's personality is heavily influenced by a past relationship, leading him to be unsatisfied with ordinary connections. Also, a specific character develops very strong yandere tendencies. ### Final Verdict "Hobby Modification App" is a guilty pleasure that's hard to put down. The morally grey protagonist, the complex female characters, and the intriguing (if somewhat underdeveloped) plot create a compelling reading experience. If you're looking for a lighthearted, feel-good story, this isn't it. But if you're willing to delve into the darker side of human desires and the consequences of tampering with free will, this might be right up your alley. I'm personally hooked and eager to see where the story goes, even if I'm a little worried about the MC's safety along the way.
