Kanojo wa Rokurokubi

A story about a long-necked girl's love life:

Kanoi Natsuki and her childhood friend Itsuki visit the same school and there seems to be more between them besides friendship. As a Rokurokubi, her quirk of stretching her neck is normal for her and her surroundings, but it's not always her choice to stretch it and although she has feelings for Itsuki, she can't tell him what she feels. Ultimately, she has to go through misunderstandings and shame. Itsuki, meanwhile, manages to make any awkward situations dissolve or maybe not?
