Diary of a Handsome Man's Miserable Life in Japan

I'm Nan Xiao, a handsome man who just left his job. For the sake of my dear mother's happiness, I dragged my frail body to the unfamiliar country of Japan...

But why is there a pair of underwear at my door?! People leave food to catch prey, not underwear! And what's with the big sister? Nobody ever told me I had one!

An energetic girl, a fujoshi, and a timid giant golden retriever all show up at once. I just want to live a quiet life. I absolutely refuse to suffer a miserable life dominated by girls in Japan!
