Kizuitara Kiss shiteta: Rinjin no Ninki Haiyuu to Himitsu no Kankei...?

Izumi Yasaka comes home one day dead-tired from work and is ready for a beer. That's when she receives a package from her family. It's vegetables. Lots of them. Unable to eat all of them by herself, she goes to ask the neighbor if he wants any. When she rings the doorbell, a really handsome guy answers the door... but he seems to be very nervous for some reason. But, after talking to him, they hit it off and have a few drinks together, which leads to something else.
