Diary of a Stunningly Beautiful Man's Tragic Life in Japan

I, Nan Xiao, a handsome man who has just retired from his job, dragged my frail body to the strange country of Liben for the sake of my mother's happiness... But why is there a pair of underwear at my door? When others catch prey, they put food there, but no one puts underwear! And what the hell is my sister? No one has ever mentioned it to me! Enki girls, fujoshi girls, and large, timid golden retrievers all appeared in front of me. I just wanted to live peacefully, and I didn't want to live a miserable life of being oppressed by girls in Japan!
