It seems there's a lot of confusion about the main character's (MC) situation, which can be quite intricate. Here's a concise summary:
The MC is a man from Earth who gets transported to an alternate dimension, Korea, where he is transformed into a female Beastkin due to a lack of mana. Initially, he was 25 years old, then aged down to 5 as a Beastkin. In this new world, mana is prevalent, but the MC can't use it.
As a gender-fluid Earthling, the MC pretends to be a boy to survive as a homeless person, facing hostility and mistreatment due to their disability. After 8 years, they're nearly killed by a monster and saved by a guild member who reverses their age and form, making them an adult Beastkin.
Misunderstandings arise because the MC has developed a cautious worldview after eight years of struggle, believing that:
1. Free gifts may be traps.
2. Dirt helps hide scents, especially in a dangerous environment.
3. Stealing is wrong.
4. Reusing items is essential.
When someone offers them clean clothes while discarding their usable ones, the MC perceives it as a potential threat, considering their history with these people.
Despite initial skepticism, the guild appears to be genuine in wanting to help and is working on earning the MC's trust. Given their power, it's impressive that they choose not to exploit or harm her, which adds depth to the story.
