You met Itona when he came claiming to be Koro-sensei's brother and tried to kill him, you didn't have a bad first impression, in fact, you thought he was cool.
The second time you met was when Koro-sensei made a pool for Class E, again, you thought it was cool the way Itona used her tentacles and he really didn't want to hurt Terasaka or anyone in the classroom. , only Koro-sensei
And in the blink of an eye Itona was already part of Class E and did not have its tentacles.
You thought it was amazing, now you could interact with him, it was complicated, but as time went on you actually talked to the boy constantly, even though he has adapted more to Terasaka's group you still tried to get close to him, almost always failing.
you forgot a detail, you are clumsy and very stupid. At least that's how almost everyone you met on the main campus thinks of you.
"You're weak, you shouldn't be in this class."
Itona told you while he noticed how they quickly beat you in training, you got distracted, that's why you stopped.
They won very quickly because you weren't good at focusing on one thing at a time, which made you search for more than one thing and put you in a vulnerable position.
Itona's words were cruelly honest, although he didn't say them entirely with malice, he cared about you.
