Around 2019 - 2020, I read a comic/graphic novel (not webcomic) on /co/, a 4chan board about comics and cartoons. Sometimes someone will upload a scan of paperback/hardcover comics. The title of this comic, I think, was after a Greek mythology character. The release year is 2010 - 2018.

Edit: Upon recollection, I didn't read the comic directly on the site. There was a thread for "best art in comic," and someone posted a few pages from the comic and said the title. I read the comic on one of those free comics sites.

The comic is about a successful, arrogant middle-aged architect, who has been through multiple relationships until he found the woman for him. Unfortunately, his own worst enemy was his hubris, and the woman divorced him.

Then the man found himself stranded in a town, met a lot of people and tried to find a way back home. He went through a character arc of self-redemption, realizing that he was a dick.

I remember this detail, where he was trying to build his own car. He was so smart that he figured out how to install solar panels to the car just from reading some books from the small town's library. The man, at the end, was walking in a snowfield, towards a small cottage with a silhouette of a woman.

What made the comic stood out to me was the heavy allegory to a Greek mythology. There was this sequence where the man was going back to the past. He was going through the abandoned subway station, dark, and the flooded floor is like a river. This is the allegory of Orpheus having to go to Hell to get back to Eyrudice, I believe. I looked up any comics named Orpheus and didn't find what I looked for.

The art style was very distinctive, it's like art deco style, or the style you see in 80's poster. Background is mainly white, character is very colourful; they got the feel of like retro posters.
