So I found out that " Being a donut " has 1.3% achievement rate across the entire steam achievement progress which come as a suprised as its the 2nd lowest to achieve, aside from the full achievement.

And if you are like me and planning to get 100% achievement, you will find this achievement to be very "anti / reverse" healing, i.e the whole concept of the game is to heal people and not to fail them.

And if you are like me, you are probably 30-50% in the game and realised this achievement and thought " Crap, I dont want to ruin my reputation that I build up across 6+ hrs ".

Fear not, as this is a quick guide and takes about 30 mins to get this achievement.

1) Back Up your save data first ( dont want anything to go wrong with it ).
2) Create a new save file character . Dont care what you call your protagonist and doggo.
3) Skip every possible dialogue.
4) Collect the herbs required to heal the Myer daughter. ( Because otherwise you cant progress the story )
5) Befriend 10 NPC
6) ^ You need to befriend 10 NPC to allow the carpenter to make an alarm for your clinic.
7) Sleep and rinse everyday. Every time there is an alarm, just sleep, skip the next day.
8) Once 10 ppl fallen ill, you should get the achievement

Lastly, during this period, whatever you need to add on to your achievement, like petting your doggo or do side jobs counts as steam progression. So before you delete this save file, do what you need to do and delete it afterwards.

Thats it!
