Yes these are really great : ) the drawing is really tight, and the stories riff off manga conventions in a really satisfying way.
Personally I think the strongest one is the most recent, it sticks to the 'four act' asian storytelling format. The first one also hits the format but her pulling her head off is more of an emotive twist for sure!
For anyone interested in this four act storytelling method, it's a great thing to practice and applies to longer form comics too. It's a way to tell a story that doesn't rely on 'conflict' of one form or another. With Okellymx's 'Are You Okay?' comic:
Panel 1 (Introduction) setting scene and character - we see this girl and a boy and he is trying to talk to her.
Panel 2 (Development) developing the scene we just introduced - he asks if she's ok.
Panel 3 (Twist) something usually totally unrelated to the first two panels, although in this case it uses one of those characters - she takes her head off!
Panel 4 ( conclusion) tying the 3rd panel to the 1st two - she's answers and asks if he is ok.
In the middle two comics you messed with the format and switched the 'twist' into the final panel - nothing wrong with that, it still works - but it leaves no resolution/conclusion panel and we're just left on that final twist (I guess like a classic 'twist' ending in a western short story or something). Again, nothing wrong with it at all! Just wanted to point it out in case you weren't aware of it. For me those middle two comics just don't quite hit the satisfaction I got from the 'Are you okay' and 'Please' ones.
Uggh! Sorry for writing so much! Really love them, I'd definitely make a new series if you are releasing something with a different format, keep this one going for the four panel stuff. I'm bookmarking it at any rate : )
