I don't think quite that long, or at least I hope not... The novel-to-manwha conversion rate doesn't seem too bad for The 31st Piece. The arc is roughly 16 chapters in the novel(starting at around ch118) which I know doesn't sound like much in the world of long-running webnovels, but certain parts in this and later arcs do feel a bit too drawn out.
I forgot the title, but what I meant was: romance as the main genre hits so much harder. A little action on the side
especially with an FL MC, just makes it better. But when it’s mainly action with a bit of romance? It’s so a$$. And fr, those bromance manhwa are so good yet it hurt the most. The chemistry is insane, but knowing they’ll never end up together is heartbreaking.

Oh, this arc felt really long in the novel (not bad, just long) so I might just let it pile up and plow through it all at once... it does have a lot of great moments though.
