If you run through Scott's size calculator for the Scott Addict 20 model year currently on their website for the USA, then it comes up with a M size for you. However I had to guess on your arm length as they don't want span but just top of shoulder to wrist. I used 60 cm for that.
Why do you think a S will be too long for you? Long in what way? The reach is only 530 cm on a S and 545 cm on a M size frame.
I still believe most should try on the bike before they buy. Even if it is not the very bike you are going to buy, you can try out Scott Addicts in the sizes they have near you and then base your sizing for the bike you order on that. Or are there absolutely none nearby to try?
Here is your pic. But I don't really know what to make of it. I don't use fit calculators if that's from some fitting website or app.
