Guest starts living alone, only to find the flashy-looking neighbor is not what they expected...
About
A long-awaited life alone began with university enrollment. With a heart full of expectation and anxiety, I found the person living in the room next to mine was a black-haired, flashy guy who looked like he spent every night partying. "I'll try not to get involved..." I decided, but one day we ran into each other in the elevator. It was the worst. Or so I thought, until I glanced over and saw him clutching a massive amount of pudding and a cute stuffed dog. As it turned out, my neighbor was a super innocent, pure-hearted boy who absolutely loves pudding and dogs.
