I read a manhwa that was something “y eternity” or “y unending” or “y never ending” with the y being a Korean name. It was a dark psychological manga about high school lovers reuniting as office works. Bottom is mentally tortured at work but doesn’t want to leave, top is someone who joined the company as a manager out of nowhere. Bottom has brown hair and top has blueish black hair. The vibes were really dark and the typography of the panels really stood out, like unique spirals and really showing the mental descent of the bottom.
