i suspect the author made that the ending out of spite considering she went on hiatus multiple times out of spite already
Out of spite?? Oh my god
Wait why was she spiteful?
because of people uploading her manhwa to illegal sites like this one they never stopped despite all the hiatus breaks she took to get them to so im guessing she had enough
Oh damn
Besides the ending being absolutely terrible, it makes 0 sense that Isaac is the killer when MOST of the killings happened whilst Isaac was with Giselle?? Talk about a story going to shit
