I really liked the first couple and how the Omega resisted his fated pair, because he was in love with his best friend(childhood friend) and lover of six years. I wish we could have seen also a scene for the Alpha resisting his pair, but it seems he never met him/her. The story seemed to go too fast most of the time, with scenes changing from panel to panel and skipping days/weeks or even years. The 2nd couple was ok, but I wasn't so invested in them.
I feel like the first story would be more suitable for a medium to long piece. Their teenage years was barely inexistent and we just skipped years into the future where they were already dating. It would have been nice to see their relationship develop. 10 years into them dating and they were still facing basic communication issues just didn't sit well.
The second story was quite fun, and it being short wasn't actually a problem. Better pacing than the first since they were two strangers who had just met. Yes, the ending was a little rushed to wrap up but it wasn't that much of a big deal.
