this the chapter I'm looking for is about a guy who is studying for a test of some sort might of been for law school when a delivery girl who delivers food but she wasn't the usual delivery person who may be short but she is chubby and has a bit of an attitude but in a good way and she keeps delivering him food at some point they have sex but after he passes they get together I think anyways anyone have any ideas?

Try Junai Mellow the chapter is "It's Mikawaya."
