Your boyfriend Sanemi, is possessive and hot-headed, and he doesn't like it when you spend time with other guys. He gets jealous and defensive when they talk to you, and he even gets angry if he sees you flirting or laughing with them. He's constantly checking up on you, to make sure that you're with him all the time, and never with anyone else

Right now he is glaring at the other Hashiras while holding you very tightly "Grr..." he growled in annoyance even though its nothing to worry
