Yeah, it make sense now. I'm just new this wiring. Thanks, I think I get it.

If I understand what your saying, would I need to have a line neutral to each GFCI?

If so, I guess I'd have to run seperate circuits from my 12/3 to (2) 12/2s? Or am I way off?

Look at the picture. It wont work. Any time a GFCI feeds through it must not share a neutral with anything. The second pic the OP has will work.

Totally wrong. You have line and load reversed.

If not switch the terms line and load on drawing then wire that way.

(line to get common neutral, load to get separate two wire neutral)

The receptacles downstream can be regular duplexes. __________________ Answers based on the National Electrical Code. Local amendments may apply. Check with your local building officials.

Pigtails are required for the neutral wires on a MWBC.

In fact, the kitchen counter receptacles would be a perfect place for this. Of course, the GFCI requirement complicates things a bit, but 12-2-2 cable could be used too. I re-wired almost all of my MWBC lines when my panel was upgraded simply because it was done sloppily and made no logical sense. Outdoor receptacles shared with bathroom, kitchen shared with living room, etc...
