I don't know why, but I feel like I have to find out what this manga is and read it because I've only read the description (It was probably just one of those days where I wasn't thinking straight but still caught a few things here and there). I have no idea on what the title is but I do remember a bit of the summary which is this: There is a girl who is continuously bullied and tormented by her classmates because she looks both vulnerable and average(?). But one day, a new girl shows up who catches the eye of all her classmates because of her beautiful and dangerous(?) look. They figure she is a transfer student but instead of going to the front of the classroom, she instead goes and sits in the seat of the bullied girl.
I would really appreciate any feedback. 😀

Alice came to a fork in the road.
"Which road do I take?" she asked.
"Where do you want to go?" responded the Cheshire cat.
"I don't know," Alice answered.
"Then," said the cat, "it doesn't matter."

The description has been changed now, but it's probably Otome x Ranbu. Maybe.

No, that's not it 😢

I don't think it's what you're looking for, but it kinda falls along the same grain.

Well, theres Change 123. Toward the end I think she gets stuck in changed form for a bit.

And ...watching Seto no Hanayome theres an episode where the class rep removes her glasses.

Sorta sounds like a removing your glasses trope. You know where the nerdy girl takes off her glasses and lets her hair down, and its an entirely different person. so its too hard to identify Simply from what you've said. Its a common theme.

Maybe Red Lion

No, I checked them and they are not what I'm looking for 😔

Do you remember anything else? ANYTHING at all? Even a little will help! 😛

Do you remember any angels or fairies or demons or magic kittens or....?

Was it Yuri? I remember a manga summary along the same lines, though I didn't read it. That on'e Yuri, though.

There are times when you will miss what you never had. I wonder how you will find what you so desperately need.

It's one of the shoujo beauty transformation ones right?
It should be one of the ones on this list.

right now my bet is on
Why Do You Love Me?

Urrghh.. It's so familiar like I've read it before. But I don't see anything on my list. Must be the time when MU was unknown to me still. Now my head's gonna explode trying to remember. >3<

Hmm...will try searching again but for now, is it Kare First Love? I've read it a long time ago. I just know she becomes beautiful. Hmmm....

I do remember that she becomes more violent, especially when her fellow female classmates try to continue bullying her but they ultimately fail when they feel like they won't live much longer because of her aura(?) I think that maybe a love interest does come into the storyline but its NOT Yuri or Shoujo Ai. And I'm not so sure about a supernatural presence.
