Though I understand the “turning small” thing makes the story more unique but i will also say that it’s questionable, just hope it will be comedic relief .
With how large the crossbow is compared to the chair and table, it’s gonna get stuck the moment he tries anything, plus he uses more time to even get it since it’s angled upwards.
Though I like this, it's unlikely that this is going to get serialized mostly due to the main obstacle of the story, the entire reason why she even crossdresses, already revealed and solved.
