New school, new fears

Shiro mizune just got into his new high school, Shizuki high school, which is supposed to be a school where everyone is nice and treat people fairly.
Well, it's the opposite.
Everyone treats a suijaku, like shiro, like little toys. He already has anxiety, depression, and Post traumatic stress disorder. Their leader, Itzumi Suzuki, tells everyone that they can do whatever they please to him. Itzumi's best friend, kuro kimse, is also a friend of Shiro. Will the leader find out Shiro's secret? Will the leader and the weakling fall in love with each other or will Shiro give up on life before it happens?
