It feels like the mangaka is trying to sell the heroine as a strong sexy woman and I like strong sexy heroines. But this girl is still SO. WEAK. I want a really badass woman who is confident with her gender and sexuality, smart, independent, not afraid of speaking her mind, and is able to tell those sexist boys that they're WRONG. Where are you my much needed feminist manga heroine???
But tackling issues like rape and victim blaming is a major plus point for this manga. Wish it was handled better tho. So much potential wasted.

Have you read Tokyo Crazy Paradise.

This dude is perfect! Sure he has that issue with love and commitment but whatever. Don't we all. I mean, not a lot of guys will immediately get that you're on your period because of some aspirin and be so gracious and not disgusted by it. He even made her hot chocolate and a hot compress!! Seriously! Not a lot of guys will do that! I need man like this in my life. Someone to give me what I need when I'm on my period and at the end of a bad day. #WhereAreYouMrRight??

I thought omegas who have been bitten get sick if they have sex with other people who aren't their mates.

Tbh, I think it depends on who writes it but, I noticed that it was always omegas that they'd take in, probably if it is between omegas then that's a difference case? XD most of the time this "sickness" would be shown if another alpha forced a bitten omega to have sex owo but who knows, maybe on this one is slightly different. (づ ̄ ³ ̄)づ still glad they're all happy now.

As far as I know that's only the case during their heat.
When the bitten omega's in heat and another alpha/beta/omega tries to have sex with said omega, it would result in vomiting/sickness in general. Outside of heat nothing happens....but I may be wrong OoO

In Remnant, they would still get sick outside of heat. This could be author preference. However, Ai no Makoto is linked with Romantic Joutou universe wherein omegas get sick when having sex with someone not their mate in/out of heat. So.
Either there's a special omega to omega magic. Or. He doesn't get sick because Seiji is there too.
But there's so many things going wrong here.
1. The handshake that turned into fucking
2. The fingering at the beach with people everywhere
3. And O. MY. GOD. What is that sarong/swimming trunks/diaper looking thing!?
