we never find out what happened to duna's contract after she went back. we never find out why she stayed in the industry, what the deal with director assface is, none of it. By far my preferred ending if we had to be subversive of clichés and Joon had to end up with someone, would have been that Joon ended up with someone not Ira or any past love interest, and Duna just continued to do her own thing. Also Joon going back to Ira feels very and I mean very rushed and like a last minute decision by the authors part. Which as evident by the author creating a side story just to justify the relationship seems to be true. It feels like the author thought to themselves that they can't have Joon end up alone and they had already set up hits that he may end up with Ira so wtf make that the ending. To me more realistically, specially after seeing friends fall in love as deeply as Joon did with Duna, Joon would have either waited several years before being ready to date again or would have just waited for the impossibility of Duna coming back. Out of all the possibilities of Joon and Duna not ending up together by far the best and my preferred one would have been that we get several chapters of time skips or something of Joon working to really get over Duna and the ending having him either be happy alone or him going on a date for the first time in several years. This story the cliché of Duna and Joon working out would have worked way better than Ira and Joon ending together or really any other ending. Tbh the pacing of the story really undermines what ever relism the author tried to shoe horn at the end. Had the author spent a hundred chapters just showing us how Joon got over Duna and stuff the relism would have hit way harder and would have probably made for an amazing story but the truth of the matter is that they literally spent 20 chapters breaking a relationship hundreds of chapters in the making and showed no development of the characters within the actual story and instead made a whole side story just to justify their bad ending.
