LMAO the rabbit scene was so funny, yeah for the princess it's all cute and fluffy, but for adventurers it's their livehood. I'm glad the author decided to make MC ready to kill the rabbit, he's a seasoned adventurer afterall.
Also I hope they don't discover his identity for a long time, to me the Manga's is only interesting while MC's identity is kept hidden and he keeps being a lazy bum. If his identity is exposed soon, then I'll drop it because it will become boring.
