This is as brainless a story as you can get, without it being on purpose for the sake of comedy. Does the MC consume lithium meds without any prescription or why do his emotions seem so flat? The prince literally crippled him as a mage, fully on purpose, yet the dude doesn't seem to care and even goes back to work, to the very prince's castle, the next day. Jesus Christ. Only a Japanese company slave could possibly write something like that. In Japan, if your superior at work gouges your eye out, you won't protest, you will ask him/her if they want the other eye as well. Then you continue your work full of gratitude.
