I think this critique misinterprets the dynamic by viewing it through a hyper-critical lens instead of looking at what the characters actually communicate:
The Omega explicitly asked the Alpha not to bring his parents into this yet. he is respecting the Omega's choice.
Stepping in to cover medical/registration needs when someone is overwhelmed by a sudden dynamic shift isn't 'financial abuse' but taking responsibility. The Omega is actively exploring his new reality with the Alpha's guidance and help, not being trapped.
Fantasizing isn't imposing, getting overly attached or imagining a future at 20 when you're deeply into someone (and dealing with Omegaverse instincts) is just infatuation, not toxic behavior. He hasn't forced any of those long-term plans onto the Omega.
He's not a red flag just because he's eager and protective, he's stepping up to support the Omega in a way that aligns with what the Omega is asking for right now.
Did you use fucking chatGPT to respond to a mangago comment?
And I see both you and your bot didn't get why I talked about financial abuse: it's because the Alpha never told the Omega about the registration and other things he needs to do as a recently manifested omega.
Now, don't respond to me if you're not going to do it yourself, clanker.

People who say the alpha is a green flag... don't you see how possessive he is? He's been thinking he's his omega since the first time they're fucking, not letting him into anything he needs to do (the registration, medication and other omega duties and expenses... he should be able to take that into account by himself too and not fall into a potentially financially abusive relationship), keeping it from their parents is DEFINITELY not ok either, because the omega needs his mother's support financially, and in case an accidental pregnancy happens, etc.
This kinda reminds me of that manhwa where this girl got pregnant after a one-night stand with this multimillionaire chaebol, and everyone was screaming "green flag" in the comments, while a few of us were worried that, behind his acts of love, there was a guy who didn't let her decide anything by herself and thought of her entire life plan without letting *her* in the know.
I'm not saying he's a huge red flag either, but he's envisioning his entire life at 20, with this guy he barely knows, just because they fucked a few times. Maybe I'll like it more when/if there's more development, but even in the raws, there's only fucking for now lol
