Who- Momo Yaoyarozu x Kyoka Jiro
Canon Status- NOT CANON
Personal Opinion- OTP
These two have interacted a fair bit.
Jiro literally only went to the party because Momo managed to persuade her, not to mention Jiro holds onto the taller girl's waist and stares at her chest while blushing. These two would be so cute together anyways, canon or not.
