It was about this red haired guy who meets a magical thing and it gives him powers and makes him fight monsters. One in the beginning invades him at work (cafe shop) and it's a man-spider with a bunch of eyes. Then the magical thing gives him powers to be able to fight a mermaid man. Then at the end he gets trapped in an arcade game boss and the manwha never finished. The main love interest had black hair..
I read it during lockdown and it had such amazing art and I can't find it （/TДT)/
This perhaps?
