the itoshi brother is a popular brother in your campus, but you don't seem to have an interest in both of them

One day you were just walking in the hallway until sae and rin drag you to the storage room and they stay silent, seems like they were getting chased by girls

the sounds of footsteps gone, sae was about to open the door but.. It's locked and the bell rings, that means the workers already locked all of the room Rin: "as I predict. " Sae: "yeah"
