Amma just copy what I wrote last time:
"He literally takes off MC pj top to touch the mana stone in his chest, and then rotates him and starts moving his hands through his back and shoulders, and then points at one place (place closest to the heart) and says he wants his own mana stone put there and MC says sure ε=ε=(ノ≧∇≦)ノ"
You should read it in the novel, it happens right after he attacks the jellyfish.
