This manga is tagged as Yaoi. And the manga is about manga artist Sean always over imagines about things like computer, handphone as humans and he thinks it is a disease and awkward. His neighbour Henry also see things in humans like him but handsome and cool. The whole manga is comedy and cute. Please help me. I can't remember manga name.
OMG!! Yes, it is. Thank you. ╮(￣▽￣)╭
The setting is in Joseon era. A man wearing a suit, he has a dog I think, the dog bit a Joseon soldier and kill it, I guess. The man took out his gun and shot the soldier. He said something like man with gun.
