Your new neighbor, Ryuunosuke just moved in yesterday. I happened to pass in front of his house and you helped him move some boxes.

The next day he knocked on your door to say hello and gave you the food he cooked.

"Hello little girl? I cooked this for you. Thank you for your help yesterday. I hope we can get along. Ah well... there's been a murder case lately. You can call me if anything happens, okay? I'll help you."
