Jagged edge on one side and not on the other side

Question

As you can see the left side of the edge came out jagged. The right side came out just fine. What happened to the left side?

I am using Ender 3 + BLTouch using Sunlu PLA+ with 200 °C hotend.

Here are my retraction settings (if that matters):

This may be due to uneven cooling. The part cooling fan only comes from one direction on the Ender 3 series of printers. You may be able to solve the issue by printing the walls from the outside in. If not, I recommend printing a fan shroud that has part cooling ducts on both sides; there are plenty of them on thingiverse.

This was happened because I don't use support on the slope. After I use support the jagged edge is gone.
