This isn't exactly a video game, buddy. This is real life. These people have lives, houses, and common sense. How would you react if somebody came into your house at 3AM? Why are you awake at 3AM? Why does that fridge smell like blood?

It's best not to get the police involved in your whole, murdering situation, now is it? Hide the body well, make sure the police can't just see her out in the open, every day, the police will come question you, so you best be prepared...

And speaking of the body...

The body can be moved into various hiding places around the house. And hey, you have a giant field out in your backyard, why not try to bury her?

Speaking of your backyard...

Farming is a key part of your income, so you best do it.

As of now, you can't really man your usual crop selling shop, so you need to sell it directly to the shop owner, Bubs. You need income to pay for house expansions, and maybe even items that'll help you deal with the body.
