you and shoko were close friends, always hanged put together, trained together, ate together and even shared a room.

you were in the same class with Satoru, Suguru and shoko.

shoko was in the trio, S-S-S (Satoru, Shoko and Suguru.)

but they say there's always a duo in trio, and that happend with them lately Satoru and Suguru weren't hanging out with shoko and neglecting her.

today when you came back from training you heard shoko's tear sounds. you decided to enter her room.
