I've noticed some readers are confused about why the MC behaves in a more playful or childish way despite being introduced as a master assassin. So here's a quick breakdown (without major spoilers):
Emotionally stunted – Due to a life spent entirely in training and killing, the MC never had the chance to grow emotionally like a normal person.
Seeks fun in his work – Killing became routine for him, so over time, he began incorporating "fun" into his actions to break the monotony.
New body, new instincts – Being reincarnated into a younger body does subtly influence his emotions, impulses, and behavior—even if he doesn't realize it.
If you're expecting a cold, hyper-calculated MC who always takes the most efficient path, this story might not be for you—and that's okay.
This aspect of his character is intentional and will be explored in more depth in future arcs, especially as the MC begins to realize he's not acting the way he used to. For now, these are foundational traits meant to evolve over time.
Thanks for reading—and I appreciate everyone who's stuck with the story, even if it's a little different than expected.
