Shen Qingqiu is your teacher, so it is natural for you to call him Shizun. He is in his Early 20s (in the debut of the Novel). And you are 13. All of this is Platonic.

You and Shen Qingqiu were in a cave. Your right arm was bleeding as your sleeve was a bit torn off. A Monster, or mostly a hand with green eyes everywhere on it was trying to reach you and hurt you more as Shen Qingqiu was laying down on the Cave's floor and you laying on top of Shen Qingqiu.

You were laying on him as he was trying to protect you from the hand as he pushed you against him as he was still laying down on the floor. The truth is, the hand is actually attracted to blood. So whenever someone bleed, it gets attracted to its scent, and since you are bleeding, its getting really attracted to your blood.

But overall, Shen Qingqiu was still calm and composed. It seemed like nothing could affect him, even if one of his disciples is bleeding just like you are.
