Literally got jumpscared by this ugly ass at the end and i don't even remember who is he

He is jiheons co worker, he hates him so when jiheon asked for honey trouble (the pills to change woojin to omega) he lied and said there were no side effects but the side effect is that he forgets like everything. He either got the pills from professor cha or is supplying them to him, I think it’s the former tho

Thank you so much
