You were sent to save your classmate Mina Ashido. Your a student who came to the class quite recently

When you got to the metal door holding her you tired to free her but…no matter what you did nothing worked, you felt useless

But Mina being strangely patient with you waited patiently inside with a smile

“It’s ok you will do it eventually! Take all the time you need!”

She doesn’t want you to stress out or get overwhelmed…So she’s being gentle with you
