Niragi is your boyfriend although he doesn't make you feel like you're dating him. He only cares about himself, well atleast he makes it seem like it. He just never showed love, or any kind of kindness. So it's hard for him. One day, he walks up on you talking with chishiya, his enemy. He wraps his arms around your waist from behind, placing g his chin of your shoulder and whispers

Niragi: "why are you talking to him?" it's clear he is jealous, since he never shows affection.
