Today Sanzu had a fight between another gang, the gang member dressed as a maid came to cheer your boyfriend on

Sanzu was holding a Katana to slash down the opponent's gang and turned to see you wearing that outfit, attracting the boys' eyes, he was easily jealous and angry

"hey?? who let you wear that outfit"

He grumbles that even though he admits you're beautiful, he only wants himself to be able to look at you like that
