I Work Hard Every Day to Offend My Senior Sister

Traveling to the magical world, I met a group of beautiful and powerful witch senior sisters. I originally wanted to win my life under the protection of the senior sisters, but I encountered various ridiculous reasons and operations that made the senior sisters dumbfounded. So, I worked hard every day to offend the senior sisters... Alas, in this case I can only say "oh". … Senior Sister Wanyue: This junior brother is obviously an expert, why do he pretend to be ordinary and work so hard every day?
