@LemonLies checking chinese and koreans scans, there is no gap, like YouSquiddingMe said, 103 here is 107 in raws and this one is right up next, this happen usually when the chapters get released in parts so the chapter number kinda move and then change again when they get combined into 1 chapter in the volume, when a new volume get released, that is the only way to confirm the chapters numbering, and hell this is a split chapter too, it say "part 1" in the title, tho didn't get translated for some reason lol
like for example, chapter 96 here in mangadex, is chapter 97 and 98 combined, and then chapter 97 here is actually 99, 100 and 101, so you gotta move chapters numbers to add up to 108 that is this one, here another closer example tho, chapter 102 here got released as
106 in magazine, from the 1st page to compare, and you can find chapter 108 as
chapter as 104 too, so is even more confusing
