Hello darlings!!! its me ✨ SUGAR✨ i've read alot of my comments about y/n's quirk so lemme explain it better for you!!
Y/ns quirk is actually nightmare where see is able to show people their darkest fears she is able to see them but only by her choice because if she chooses to see them then their fears are attached to her so she never looks into them because of two past experiences. Now with updated quirk she is able to allow people to see their hopes and dreams and if she wants to she can also make see their biggest fear. Y/n quirk doesn't attach herself to other people which means she cannot see or hear what they are thinking of unless she uses her quirk on them again.However if she and the other person desire an close bond And both parties give consent to feel , see and know what each other are thinking then something like this happens.
Then again she already has done this with hawks/ keigo which is how she knew he was thinking of something perverted, best part about this bond is that they are able to feel when one is near like with her and aizawa.
Welp i hope i explained this good and easy for you to understand.
Bye-onara!!✨✨✨🌟🌟
